Don... "Sounds" (excuse the pun:) like you've got a glasspack (free flow) on there, maybe a Thrush or Cherry Bomb. These are "straight thru" designs (as opposed to the "baffled" stock (or Midas/Meineke/ Walker, etc.) system. It may also be the optional "GEX" straight-through type I've see advertised by MiniMania. "Straight thru" design with sound deadening packed around the "open" core allows for perfomance and/or gas economy along with allowing for a cooler running engine due to the easier trip the hot exhaust gases have outbound. allow the engine to run a little cooler as well as the exhaust...

Thought that's what sprigets were supposed to sound like! Although I am only going on my Ex racing frogeye and the 1500 I last drove 12 years ago.. and the exhaust fell off this when I layed it up IIRC Stewart "Ford Prefect" 25175... MORE
Seems the PO's of my purple 73 wanted that race car sound, well its not modified to be a race car and the sound level is annoying especially out on the freeway, like riding on top of a WW2 buzz bomb. It's a fairly new muffler and pipes so its not loud because of age. The question is, what are the considerations I should keep in mind when choosing a new muffler? Don't care if it is stock as long as it fits and is correct for the engine which I suspect is bored out a bit but otherwise... MORE
You can certainly put a RX7 rotary in a Midget, but you'd better put in the RX7 trans too. There'll be a lot of parts which will have to be fabricated - exhaust, guage hook-ups, cooling, etc, etc, etc. You'll then have a car which will go faster than either the suspension or brakes can safely handle. I'd suggest you just sell the Midget and buy a RX7. "Jeffrey Holmes" 25076... MORE
Interesting experiments, Paul. The most simple well-working PCV system I ever had came on the '67 engine 5 main bearing engine which I installed in place of the 3 main bearng which came in my PO'd '64 MGB. Factory PCV valve (rubber diaphragm) intake manifold mounted breathing through the liquid/vapor flame arrestor mounted on the front of the timing case cover with matched vented/filtered oil filler cap. Replaced the diaphragm once and filtered cap once in a while. And introducing a little water into the intake manifold once a year will help keep things clean. There are also a... MORE
...might be on subject...but not 'specific' to the conversation.... I've been studying (extensively) the various emissions re-breather systems used on the various years and models of LBC's. Why? Trying to come up with a system that won't dump oil all over the back of the intake valves. Any of you that have ever pulled a head off an engine that has had a bit of blow-by due to worn rings, knows what I mean. The vapors (due to crankcase pressure) being discussed here, dump all that oil into the intake and end up burning onto, and crudding up the... MORE
OK, Claire...let's work the problem a bit. You keep talking of a vapor/oil seperator. Where exactly is this part located on your engine, if not on the timing chain cover. I ask specifically because the year of the car may not be the year of the engine, Claire. Fr'instance, a late 10cc engine (1098) would have the vapor/oil separtor cannster located on one of the valve lifter side covers under the intake manifold instead of attached to the timing chain cover like the later 1275 engines. Factory stock PCV valve: The "appearance" of the rubber diaphragm can be decieving.... MORE

I've just recently bought an 1967 Austin Healey Sprite that was in need of some TLC, however I've also since found out it's got a few parts 'missing'! One of those was the flame trap that connects through flexible hoses the block to the inlet manifold (it doesn't have the 'Y' connector). Since fitting the missing part it now won't run properly. It has started to kick out loads of white smoke & a little bit of blue. We've compression tested the engine, fitted a new head gasket & set up the carbs so they are fine. We've now... MORE
Hi, "Cheers"... Let's get our parts straight, first. I am a little confused by your terms and the way they are used. The PCV system on the '67 is very simple. It consists of a factory diaphragm type PC V valve mounted on (in) the inlet manifold, which is fed via a flexible hose from the vapor/oil separator (aka "flame arrestor) mounted on the timing chain cover on the front of the engine. It is a "graduated orifice" (diameter of hole specific to the application). It is an "outlet". The "inlet" consists of a graduated orifice embedded within the... MORE
Kevin, 1500 run pretty clean ususally. I got a '75 to pass in California without a working (gutted( air pump and blocked air injection lines. I would think the EGR valve is essential though. Make sure the carb is properly tuned at that you choke is complete off with the car warmed up. I would run the carb as lean as possible and do a fresh oil change before having it tested. I don;t have a lot of experience with SMOG cars, so maybe someone else has somethig to ad. Gerard "gerardchateau" 24721... MORE
Hello all, I just took my 77 through emissions testing and it came up short. It passed the Hydro Carbon & Carbon Monoxide tests with ease but was just over the Nitrus Oxides limit. The car is missing it's EGR system. Are there any tweaks to the carburation/timing that might improve it's chances? Thanks! Kevin Milwaukee, WI "kari_kevin" 24719... MORE
Hello all, I just tried to get my 77 though emissions and came up short. It passed the Carbon Monoxide & Hydrocarbon portion with flying colors but was just over the limits for Nitrus Oxides. My car is missing the EGR system & I know that would help. Short of replacing the missing valve, etc. are there any "tweaks" to the carburation/timing that could help it pass? Thanks!

Kevin Looks to me like it screws right into the top middle section of the exhaust manifold. Mike mk2sprite@... 24596... MORE
Hello, i'm new to the group and I am looking for just a few bits,..mostly a period radio, a stock muffler, and (I realize its a stretch and yes, I know I can get one on e-bay or through the standard mail order companies, but it never hurts to ask) a black carpet kit for my 1962 midget. I also have a spare copy of John Blaggots book "Mighty Midgets and special sprites"...its very nice book and its in perfect condition. aaand while I have your attention, I have oil running out my back left hand side rear wheel...

Thanks for the info! A quick question: You described how the EGR valve hooks up to the air intake manifold. How does it connect to the exhaust? Thanks again, Kevin "kari_kevin" 24482... MORE
Hello all, I'm looking for information on how the emissions controls are configured on a 77. Specifically how the Air pump & EGR valve are setup. Right now on mine the air pump feeds though a check valve directly to a connector on the tail end of the exhaust manifold. Did that year have a diverter or gulp valve? The EGR valve is missing. Did it have one? How was it hooked up? There is an elbow connector on the air intake manifold that isn't hooked up to anything. I've been looking at pictures of engines on the web,... MORE
Thank You for the exaust and intake manifold, sorry the mail was so slow delivering payment to you, so I canceled the first check. The new check is in registered mail to you, you should recieve it by 15 Aug, I will log on to USPS to see if you sign for the mail. Thank You Bill Burger "ooohaynow1" 24386... MORE
Well I've gone and done it..the '60 is coming apart. Engine and trans are out in preparation of a complete refurb. At the very least this will include new inner and outer sills, maybe floors and possibly rear spring boxes. Paint will be redone and interior gone thru. I have a 1275 and ribcase waiting to be rebuilt and installed, along with Weber sidedraft etc. I am seeking suggestions on cams, porting and header. This will be a "quick" street car, neither a daily driver nor a "road racer." Any advice will be appreciated. At this point my proposed... MORE
George... I think you have three problems: 1.The intake manifold mounted PCV system uses the vented/filtered oil filler cap to provide for incoming air. 2. The most effective crankcase scavenging consists of a feed to the PCV valve from below the pistons. 3. The "cover" to the old mechanical fuel pump fitting on the forward left side of the block just above the flange can be used as a "source" for relieving lower crankcase vapor/pressure in place of the old takeoff on the stock timing case cover which no longer exists, in consideration of your new timing cover set-up... MORE
Simultaneous smoking exhaust and leaking can be caused by build up of crankcase pressure. The A-series doesn't have a real rear crank seal, and even a slight positive crankcase pressure will cause it to leak, maybe lots. The same for exhaust smoke. With the engine running, remove the oil fill cap and put your hand over the opening to close it off. You should feel a slight vacuum - not a lot, maybe, but enough to feel. Increase engine speed and feel that too. If you feel pressure, even slight, that's a problem. New rings and 200+ psi sounds... MORE
Hi again: Thanks to all those that helped answer some questions I had about the carpet, that was most useful. I found that I have snaps on the footwell carpet and the trans tunnel. Question: The rear wheel arch cover pieces seem to have a small vinyl pad sewn into them. I assume this is a wear pad for the top frame? Or could I have placed this piece in the wrong spot??? They sure seem to belong there. Can someone tell me if there is a vinyl pad on theirs? Thanks Rio "Rio Rafael" 24319... MORE

OK, the area around the spring boxes on the MK1 while physically solid has had patches of steel welded over other patches over the years, and the whole area including the rear inner arch and the reinforcement running round the boot floor like a chassis rail is quiet simply a mess, the whole lot needs cutting out and replacing. Now many years ago my dad and myself cut up a frogeye, and I have had to repair this area on my 1500 shell, and I can tell you one thing for certain, the 1500 shell has within the triangulated...
