Gear Head Needs HELP! 2.5L Camshaft issue
Ok, here's the Deal, My buddys 97 TJ is siting in my garage after being worked on by another "friend".
The alleged friend has done all kindrs of tune-up work to it for a rough running issue. Long story short, it was towed here after all the work was done. it would at least run before.
First thing i see is the shiny new distributer, sitting 1/2 inch high and the hold down ear broken off. First thought was the said friend had really F*ed up that job, however further checking shows that excessive camshaft walkthe problem here. After tearing into it, I see no mechanical device for keeping the shaft from walking foreward towards the timing cover. (yes, the bolt has made a nice cut in the inside of the cover.)
How the hell is the camshaft secured?
I am curious how this turned out.
Actually found this doing a search for camshafts in Google....
Just double checked a online part diagram and no thrust plate is listed. Usually flat tappet cams are ground with a 1 degree taper on the lobes. This helps the lifter to spin in its bore. It also helps the cam to be pushed back in the block by spring pressure. That makes the cam timing gear the thrust. But the cam should be pushing back not forward. I would check the T Chain and gears. If the chain is straight and the cam gear is out from the block then he may have installed the wrong gears.
Shoot just noticed old post.
