My Comanche -89 with 300 000km need some care...and I need some advice.
There is a hard knock under the engine and I thought it was the flexplate but the bolts was not loose at all and I can't se any cracks in the plate.!?
Here's the knock:
When I listen to the engine with a skrewdriver to the ear the sound comes somewhere from the rear of the oilpan...but it's hard to precise.
I tried to disconnect the wires to the sparkplugs one by one but I coulden't hear no difference.
Is it the mainbearings or what?
There is also a ticking or rattle during acceleration or under load.
(It's not pinging due to timing)
Could that be from bad mainbearings?
