Jeep patriot timing chain slipped is this a big job for mechanic to fix
no symptoms posted, no events stated.2.4L DOHC Non-Interference (Valves may hit if camshafts turn out of time)
2.4L SOHC Interference
seems yours is listed as 2.4L DOHC,
no mention of chain noise before or now , at failure....
here is the interference page on 2.4
this means that the engine is free wheeling on the DOHC
so long as one cam dont spin and the other is stopped.
or one cam slips time and out of time with the other cam.
and the valves crash..........
on all DOHC engines, i respect them. i do a cylinder leak down
test by hand, no craning the engine with the starter inviting said CRASH.
so if the cylinder leaks near TDC on the compression stroke
or if by hand turned over gently by hand spark plugs out I feel hitting
I STOP. and THINK then take action
what is action, i pull it down and look to see if the marks are OFF.
if off , i fix that then repeat the leak down test.
if that fails, the head must come off
its easy to make it worse, the key is dont/
