My 88 MJ has a tick, especially when cold, but it doesn't go away completely. I've put the stethoscope on the valve cover, nothing. It has a slight exhaust leak (proven when I seafoamed it) towards the rear of the engine. I stethoscoped the manifold, all the front components are new cause I've revamped the thing (water pump, alternator, A/C compressor, P/S pump, harmonic balancer).
So my question is: I know the AW4 has flexplate bolts that can work loose and cause a tick, but is the same with a 5 speed? Can the flywheel bolts work loose and cause the same tick?
OR
would the exhaust leak increase or decrease the tick
as it warms up?
Like I said I've run the stethoscope all around the engine bay, top end, oil pan, sides of block and cannot isolate the ticking. I've also changed the oil twice, seafoamed, MMO the first change to clean things out, Lucas oil stabilizer the second change. No difference in ticking.
When it's at operating temp the tick is less pronounced but still there at idle. When I'm reving or running the tick SEEMS to go away, but I know the ticks just get closer together and blend in with the engine roar. It doesn't seem to affect the performance of the engine, still runs very strong without any stuttering, backfiring etc.
