Nope. Grade 8 is stronger is tension and in shear. BTW, there are plenty of grade 8 and stronger bolts in old cars. They just aren't marked as such. Don't believe that? Okay, torque up some grade 5 rod bolts in your (pre 1980) L88. Can you say "bang"? "Jeffrey Holmes" 25521... MORE


Well Don May.... The crankcase takes incoming air from the charcoal cannister through a "graduated orifice" feed tube mounted on the valve cover, assuming the valve cover has a non-vented oil filler cap. The "exhaust" side would be the hose coming from the cannister on the timing case cover which vents into the intake system via individual hoses which feed a "graduated orifice" within each carburator. In this instance, while the engine is running, Kevin removed the oil filler cap and noticed no vacuum or pressure. So even though Kevin states the individual hoses to each carb appear pinched,... MORE


Kevin... You engine looks nothing like the engine in the Haynes manual? Hmmm.... Well...a picture is worth a thousand words, Kev. Those hoses to the carburators from the cannister on the timing chain cover should definitely be clear and open.... no doubt about this. If the valve cover was on the engine when you were running it, then with every respect, Kevin, there is no way you could tell where the oil was coming from... the oil filler hole is too small to provide a decent view and through this small hole, not enough light in there...to dark in...

I'm in the process of rebuilding my motor(1275+). I had the crank lightened (wedged,-2lbs), balanced and polished during it's stay at the machine shop. The block was cleaned and new main bearing were installed. When I test fit the caps, with 40lbs torque but without the Thrust Washers, the crank turned smoothly with little effort (I used assembly lube). I removed all the caps and then reinstalled them with new Thrust Washers from VB; now the crank needs about thirty pounds (approx) of force to start it rotating. It still moves smoothly but requires some effort. There is no... MORE


Martyn.... BTDT. You poor ba$ta-d....and I speak from experience. What we did was pull the tank, pull the sender, find youthful human being with really thin arms (my mechanic's 16 year old was on hand, thank God) and get in there with a long needle nose pliers (or whatever) and wrench the clogged up filter netting right off the steel fuel feed line. This will take a lot of patience to finally get a grip on the stupid thing to the extent you have the leverage to disloge it from it's pipe, unless you get lucky...which I hope you... MORE


Naw. It would be nearly impossible to have too much oil from the rocker assy, and the movement of the push rods (which move somewhat sideways as well as up and down) would prevent the holes from plugging up. What you've got is excessive crankcase pressure, which prevents the oil draining back into the sump. Since the engine sat for a long time, may have multiple broken piston rings, possibly a broken piston. Have a compression test done. If compression is good, then the problem is plugged up or disconnected crankcase ventilation system. With the oil fill cap removed,... MORE


Hi, Bill.... Jegs, Summit or Racer Wholesale offer some nice 4 point systems with 3" webbing that really holds you in. These are usually top brands like Simpson. They sell the mounting kits as well. The Spridget is small inside so get "pull up" types rather than "pull downs" when it comes to the seat belts (it they still offer a choice in this respect) whether you order/use the shoulder belts or not. As you already know....VB, Moss or any of the other usual suspects for the stock OEM type stuff. "Performance shops" also carry generic types that will... MORE


Check to see if the hose from the top of the oil separator canister on front of the timing chain cover to the carburetors is clogged up and if the two small inlet pipes where the hoses connect at the carburetors are not clogged up. Spray a little carburetor cleaner in them. Don "Don May" 25419... MORE


Bradsky... Milling the head slightly will have no ill effect upon anything, considering how little you are removing, assuming it had stock 21cc chambers to begin with. As a matter of fact, milling the head rather than going to flattops is the preferred way of raising the compression ratio moderately according to Dave Vizard, this having a more salutory effect on combustion/flow characteristics than a piston configuration change. For racing, the factory goes to 16.4cc chambers before they start raising compression by changing piston configuration so I guess this is the safe limit before head strength is compromised. What... MORE


Hi, Kevin... You will eventually hear from a lot of others on this I'm sure, in time. If the oil pressure is good (10psi or more at idle and about 60psi running at 3,000 rpm or better), two things come immediately to mind, considering it's coming out the oil filler hole and not out between the block/head. 1. excessive clearances in the rocker system between bush/shaft and/or 2. larger than normal pushrods (aftermarket "performance") which may be slowing oil flow back down into the crankcase as these can be thicker in diameter than stock. I am assuming the engine... MORE

"the 45 has always had a flat spot" Well, a "tendency" toward this for sure, though. Not mine! :) It came with the Weber 6" long intake manifold to begin with, and the length of the intake manifold makes all sorts of difference to the whole application in all sorts of ways. Generally speaking, longer is better for the low end. It also came with the smaller 3.5 aux. venturi's unlike some other kits which come with larger 4.5's, the smaller aux. venturi allowing earlier commencement of flow from the main system during acceleration, thus shortening the period of...

Hey... Don't knock the Perry's for your mechanical abiities! :):):) You got it in, right? And you like it, right? DONE!! First time around for anything is always a bit of a pain, in any event. Ask any girl....(flame suit "on"!:). OK..serious stuff.... David...are you running 3.5 or 4.5 aux venturis in your "45"? 'Cause the larger the aux venturi, the later the main system comes in so the longer you spend in the "progression" stage and the "finer" it's tuning must be throught out the period it's carrying acceleration between idle and the beginning of the main system....

Well it's about time. My 71 MG is back and refurbed. While it was apart for a new clutch disc, why not put a Datsun 5 speed in it? 266 cam, lite lifters, right springs, new shells on the still-standard crank, Cooper S 163 head with rimflows and ported, 45DCOE, and LCB, with a Kenlowe to cut cooling losses. Cooper S dizzy. I want a merit badge for making the Rivergate kit work. It is not easy for one who must follow directions literally. Much more difficult than it needs to be, for me, anyway.

The slope of the vehicle which tends to lean to the left is an aid in cornering. A pure performance upgrade. The factory was spitting spridgets, sprites , and midgets out by the thousands for the hopes of entering one of these brave little cars in USA's NASCAR some day.

"Now that your older (like me) you just worry more about that stuff" "What? Me worry?" (courtesy...Alfred E. Nueman) Whadya mean, Jeff?! Older? Yes, BUT...wiser!! And worrying far less. Why, you ask? 'Cause I've learned how to get more bang for the buck while "conserving" to the extent possible considering the same (more or less) perfomance level. What you say is true about the "A" series being bulletproof though, most especially the 1275 variants. Good motors.

Bob, Can't add much to your post. The same here. Until you are completely out of the SF bay area, going south more than 55 miles, the idea of just staying in the right lane is near impossible and even then, as you say, people passing someone in the left lanes who are not going the normal 5-10 miles above posted speed come up behind you at 70 plus mile per hour speeds. Then when you do clear city traffic and constant merge lanes and say travel I-5 south to southern California the traffic flow is 80 miles per... MORE


Guy W. Slower traffic staying right is the general idea but in moderate+ traffic it doesn't always work that way and it can become more a general free for all, most especially when 18 wheelers are thrown into the mix. This is theory which works until you come upon an entranceway with many cars merging, then you may find yourself forced into the middle lane in a situation wherein the traffic flow in the middle lane is doing 70 and you lack the power to merge left easily into THAT flow to make room in the right lane for... MORE


Don, The 3.73 diff from a late rubber bumper Midget will drop a couple hundred revs at 70 mph, and larger tires a little too. Lots easier and cheaper than a different tranny. I don't remember what year your car is, but if it's a 1275, 4000 rpm all day long won't hurt it. Now that you're older (like me), you just worry more about that stuff. Just FYI, I have read that the factory test, when they were building new Spridget engines, was 100 hours on the dyno at max HP. That's about 10,000 miles pedal-to-the-metal. "Jeffrey Holmes"... MORE


My 'tu-pence' : I want to be able to drive the spridget..where ever and as often as possible. Spending nuff time in garage with sons Porsche. Agree with the hi-rev's/hi performance might equal more down time for maintenance. With that in mind, and funds being available, it would seem a blend of euro-asian makes sense. But then just how far should one push the blend? If the 210 box works great.. some other power plant as well work better than the std. 1275 (or whatever ones flavor of spridget came with)? Would like to think all spridget can be... MORE


I guess what I'm saying is that although my five speed (Toyota) makes the car very relaxed at speed it is not essential for high speed cruising. In fact I'm toying with the idea of going back to a standard box and 3.5 diff sometime in he future so I can do historic road rallying in it. "Jeremy Cogman" 25211... MORE
