So I spent last Sunday night(the night before my first day of work on the new job) at a shop until a little after midnight trying to repair someone elses mistakes on a Chevy(well GMC). Puting a new engine in a friend's 94 1500. The "expert" or as I like to call him "super tech" that my friend had help him with the engine build and install did a few things I just have to note. First we discovered(after the engine refused to run). He improperly installed the distributor, was a few teeth off. now granted that is an easy mistake and one I've made many times. Next after someone mentioned the occurance we discovered he had installed the camshaft 4* retarded . Now the camshaft is too large for a TBI enigne (110 lobe seperation angle, 220 something duration). I stated that early on but it went unnoticed. Add on top of that the 4* retarded and boy that TBI was throwing a fit trying to idle. Then while trying to lower the pan to reinstall the timing cover(after we fixed the cam timing), I noticed an odd placement for an aftermarket oil pressure guage(which the truck has in dash stock...). Someone had installed it into the coolant passenger, in the middle of the block down by the pan rail(usually taken up by a plug you need an allen key to remove... I guess the factory guage was taking up the spot so that was good enough? Then we discovered that the Knock sensor had not been reinstalled. Nope the connector was busted(I assume during removal) so I guess it was deemed uneeded. So finally a call was placed to Comp Cams who confirmed the camshaft was no good for TBI and hopefully it is all getting sorted out. Fun fun fun I say. And again, some people shouldn't be allowed to work on Chevy's. I am overly confident and come off as a bit arrogant about my Chevy knowledge often enough, thats why I wasn't sticking my nose into things from the start, but I wish they would have called me in for assistance on this whole thing from the get go. yeah I'm just kind of venting. Anyone else have to go fix others Chevy mistakes?
