I have a relatively stock hot air engine with stock pistons and Kenne Bell cam (1XTB) and I was told years ago that I should have btw 14-16 in hg vac at idle. I have for the longest time only get 11 in hg. I did a smoke test on the engine and the only place I could find a leak was at the TB...

I have a replacement ECM but they did not include the eprom cover and the 2 screws with it. Does anyone have the small cover and screws to close it up? Thanks

So I ordered a reman ECM from rockauto and received it without the metal cover and two screws. I'm not sure why they wouldn't keep it with the casing but I have to find one and the screws. The core I got from someone doesn't have it either and I don't have the original ECM. Are these available...

Just wanted to see what you guys do for the preparation for winter storage on the alcohol system. In the past I have run water thru the pump and nozzle and let it go at that but didn't know if that was ok or should I do more? Thanks

I am having trouble getting the housing to seal against the manifold. I have tried 2x with new gaskets and it still leaks. The housing has been cleaned but has allot of rust pits. What are you guys doing to remedy this? Can I buy or new one or try to find a good used one? Thanks

Can someone advise what the proper plug size I need for the four block freeze plugs are? I want to use brass since I just noticed one of the steel plugs has a hole in it. I see there are different cup heights used looking at the advance auto website. I am going to replace all four on the block...

Can someone show me a picture of which way the closer shocks mount? I don't know if I have them the correct way. The hood seems to be binding right before it closes and I don't know if its the shocks or something else in the alignment. Or is it usually very tight to close. Thanks paul

Hi guys, I am trying to find some 1/4" soft braided hose for my fuel gage. It needs to be the type for push loc or socketless fittings. I don't want the rubber stuff bc over type it cracks on the outer shell and makes me nervous. That is why I want some braided weave but not SS. I can't seem to...

I have a stock 86 and the belt tensioner is squeaky. It drives me crazy. Last I new the tensioner pulley is discontinued. Is this true? What are others doing to fix this problem? Thanks

On the large connector that screws onto the coil pack module is a terminal marked J, the diagram I have shows it as "Fuel Injector timing input". Can someone explain what this does and where does that signal or wire come from? The reason for the question is I am dealing with an old DFI accel...

Looking for a complete wiring harness and ecm that I can plug in to my 86 engine and get this thing running. It's on the stand and I cannot get it to run. Using old Accel dfi system and it's not working properly. Thanks

Haven't started the engine for quite awhile and when turning on the key the fuel pressure goes up to 45 psi and then drops to zero. Is this the fuel pressure regulator not doing it's job or are all the injectors stuck open? I think they are 36 lb injectors with a KB regulator. Thanks Paul

Hi guys, has anyone had any issues with the flexplate teeth hitting the starter gear roller stop? This is a stock engine but with an aftermarket mini starter (Earl brown starter which is a very nice piece btw). The engine is on my stand so I can see things real clear. One thing I checked was the...

My starter motor engages and disengages while cranking and grinds also. I took the starter out and man is that heavy. I am getting older but still. So if I want to replace it with something lighter that is plug and play what should I look for. Plus I don't want the flex plate teeth to get any...

Its been awhile for me but I am going to run my hot air motor running again. I can't remember what knock sensor I installed or even if it matters btw hot air or intercooled version sensor. I found a GM 5 pin sensor module with a number 881654 and another # 16051654 7203 stamped on it. Can...

Hi folks, I found some sparks plugs in my work drawer and was wondering if they would work in my 84 GN? I think I bought them for it but it may have been a long time ago. They are Champion RV17YC. They may not be the best choice but are they for this application. The motor is mildly stock and I...
