Just Did my compression test today, here are my numbers

#1 150-155
#2 170-175
#3 180-185
#4 190-195

I did not do a wet test to check the first and second cylinder, I will probably do that tommorow.
What does this mean? Is it a bad headgasket? Is it worn rings? Valves?
any help would be great.
I'm trying to throw a 75 shot instead of my 55 shot and I don't want to screw something up. My setup is good, but I did replace the headgasket a few years back with what I think was a crappy one. I'm wondering if thats it. I'm thinking about taking it to honda for a leakdown test. Also the spark plugs were showing the car is running pretty rich. I like that because its safer when I'm running the nitrous.

 

Could be any of those areas you listed, gasket, valves, rings, etc... Probably the HG though if you think a bad gasket is in there.

 

You sound like you haven't had the car tuned, if that is correct, I suggest doing so before NAWWWSSSing it again or you'll risk having the same problem twice.

 

Was tuned, running rich at around 11 a/f while on nitrous. Plugs show its running rich too. I think its the crappy head gasket we installed years ago when I didn't know any better.

 

crappy headgasket?

you need to perform a leak down test in order to find out where the compression is leaking. Put each cylinder to TDC and test it out.

11's is stupid rich.....

 

Yeah, I know. I'm going to have it redyno'd when I put the 75 shot on.

 

Just completed the wet comp test results exactly as you said to do, here they are

Dry Wet

#1 150 175
#2 170 200
#3 185 210
#4 185 210

They all seem to be varying by around 25.
Also there is oil on the valve cover where the spark plugs install around the holes, also around the seal of the valve cover, and the distributer. The new spark plugs I installed yesterday are already black so I know the car is running really rich, I have no idea if that means anything. I have read running too rich can wach away some of the oil around the rings. On the dyno, it ran around 13's off the juice and as low as 11's on the juice. I know I'm not an expert by any means, but I really wonder about that head gasket. I replaced it when I had the 3 angle valve job done and don't remember what brand name it was. Also my buddy put it on, he did all the work for me back then because I didn't know crap. It is easily possible that he messed up the torque sequence, don't even know if he torqued them at all. He never used a manual I know that. That was a few years ago, I guess I'm lucky. I know I sound like an idiot now, but I just had no idea what I was messing with back then. I am just now catching up and learning to do my own maintenance and research. I am an electrition by trade, I worked on helicopters for the army, so I'm not an idiot, and I can learn. If I do need to replace the head gasket, how difficult is it? I will take the car to honda this week for the leakdown test. There is someone that had the exact same setup as me with more mods for the fuel system, and the exact same compression results who blew his engine on the 3rd pass w/ a 75 shot. The only difference was it was a dry kit. That got me worried as hell. He did not hit the rev limiter or anything like that. Also, how do I tighten my belts, where is the tensioner bolt? I've got the unorthodox pulley kit (I'm removing the crank pulley due to all the controversy), and Its squeeking at start up until it is warm.

Thanks again for taking the time out.
