So I am hoping someone can tell me what is going on. Lets start from the beginning. I have built basically a 7A-3B, 034 IIB. I had an issue with the engine and could never figure out what was wrong was only running on two cylinders and smoking like crazy, there was a few problems (Tyson helped sort through, thanks buddy). It came down to 2/3rds of my hydraulic lifters had collapsed and was not allowing a/f mixture. I promptly ordered lightweight new ones from 034 and they were shipped right out. I had pulled the cams (7A's on 7A head) and cleaned them up. re-lubed and re installed into the cylinder head. I had put her back together and the moment of truth wham not firing in fact sounded like it was free wheeling. what do you know it was broken which means what gentlemen? Bent valves. (F-WORD) luckily enough I had picked up an excellent condition long block and I began pulling cylinder heads. Got it all put back together and ping, another cam gear key luckily I had smartened up and rotated it by hand (crank bolt) to make sure nothing slipped. I rotated it about 6 times and noticed the timing on the cams was no longer aligned. F%$%^&K! another cam gear key. So finally I ran Edmonton dry of 7A and AAN cam gears and got a AAN and promptly removed the trigger wheel. I got it all set up and rotated it about 20 times to make sure nothing moved. Success and I finish assembly and try to fire the beast up. nothing.......... GRRRRRRRRRRRRRR checked compression NOTHING! so I feared the worst an *((*&*(&)(*& cam key broken, might have toasted a perfectly good head.
Why are the keys breaking? and how can I check if the valves are bent without pulling the head (doubled up MLS gaskets get expensive when you have two for dropping compression.)
please help! :frustrated: :frustrated: :frustrated: :frustrated: :frustrated: :frustrated: :frustrated:
