TJ off the road... [Archive] - Sydney Jeep Club Forum

My TJ lost power last week, and was diagnosed as having no compression in cylinder 2.
Today, the bad news. One of the 'lifters' for cylinder 2 has a hole worn through the bottom by the camshaft. The lifter was totally distorted (and some metal missing), and because the camshaft needs replacing, I took the decision to have the whole thing restored & reconditioned.

Expensive!

Hope to be back on the dirt by late November!

In better news, my GC is on the dock in Baltimore waiting to be loaded on a ship, now due to dock in Port Kemble on December 6!

Ouch, I was sure it would be the top end and maybe just a valve problem, which I guess, in a round about way, it was ;) The lifter must have stopped spinning in the bore or got limited oil. a full rebuild is probably a good idea as the oil galleries will need to be checked and cleaned out and any varnish on the lifer bores sorted. Guessing cam is stuffed as well, once the hardening on the lifter or cam wear through they don't last too much longer and little bits of metal traveling through the system (until they get caught in the oil filter) aren't going to help.

Sounds like you'll have the two Jeeps ready about the same time, decisions decisions ;)

So my camshaft is a real mess, as we expected, so I need a new one. But the guy rebuilding the engine can't source one, other than from Jeep in the USA, which will take about four weeks.

Any thoughts on who I could call to try to source a camshaft?

We just replaced the engine in our TJ for similar reasons

This might be an option, also noticed he has a second engine, might be able to get that cheaper and could do the job if you just need the camshaft.

Thanks all for help and suggestions. I thought I had posted again yesterday, but now no sign of my posting.

Thanks Heidi, I have ordered the camshaft per your suggestion. The engine swap looks interesting, but I think I have committed too much to go down this path now. I'll keep you posted as to progress.
