im really lost now, i had the inector pump rebuilt, injectors rebuilt, head rebuilt. Put it all together, it runs, but at idle it has a heavy knock then when u smooth out very nicely when u raise the rpm. The knock is there throughout all engine running temperatures. Changed all fuel filters and lines while doing the job. As far as I remember, on the old engine it never had such a severe knock. Is tere something i missed with timing? I lined up the marks on crank and cam then turned to 15 degrees atdc and installed IP. Whats up with the timing device? ANother thing i checked is the compression on the cylinders, they are all fine, around 400psi. Alternator and A/c look good. Only thing i didnt check was the cam bearing clearance, is there a spec for this?
Im really in the hole with this one, any help would be apreciated
