So bought my car with a rebuilt head around 2000 miles ago, and for probably the last 1500 miles I've been experiencing pretty much no power exactly like a boost leak. It's been running stupid rich ever since I bought it. Only mods are walbro 255, aftermarket fpr, evo iii 16g, and egr delete. I finally get around to compression testing it and its consistently ~100psi +-2. Checked
the timing to make sure it didn't skip, and it didn't. So I start pulling everything apart. All the intercooler piping seems solid and I couldn't find any leaks with a simple hand over one side, mouth on the other test. N
ot really a valid test but I trust all the piping. I end up pulling the head for a visual inspection of everything because I'm too cheap for a leak down tester. I rotated one of the cam gears while it was off once or twice I'm not sure if that screwed anything up but it seems as if there's a huge gap when my valves should be seated. My question is what's the next step? Does an automotive machine shop fix this or should i just find a different head for sale? Mine is in very good condition other than this.
