• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Won't start after cam install





Some of the valve seals are wrecked, so I'm going to replace those. However, I don't have the spark plug air adapter so I won't be able to get it running until tomorrow at the earliest. Always something. :(

The cam/crank timing is fine. The valves and pistons never contacted each other. The harmonic balancer problem (a serious ignition timing problem) is the only possible thing that could have caused this... I think.

Worst case, use some para cord in the spark plug hole. Just get it to the bottom of the intake stroke or whatever, jam as much rope in there as possible and hand turn it to the compression stroke until it gets hard to turn. and take the spring off. I don't like air, you drop that valve somehow you are screwed.

The valve won't drop if the piston is at TDC.
 


Changed all the valve seals. Got the rest of the valvetrain (pushrods, rockers etc.) assembled and torqued. I turned my motor over by hand and it is turning over WAY easier than before. No binding or strange sounds. All the valves are opening how they should. LIM is ready to go on. Can't wait to get this done.
 


It's making the same ****ing noise. OMFG. It ran okay for about 10 seconds, then all of a sudden, loud ****ing tapping. F*CK. Ughhhhhhhhhhhhhh.
