Hi guys,
I need some help with my soarer tt 91.I have a knocking/rattling sound on the bottom end.If i start car in morning(cold)then i hear for a few seconds a knocking/rattling noise and then slowly go and come back for about 5a7 minutes and go again and then i hear nothing anymore and engine runs super till next day and whole story begin again.Bearings?Someone have a idea or solution for me where i must look/check. Thanks.

i've had a rattling sound coming from my exhaust and that was because the cat was busted. can you pinpoint the source of the sound? from the front of the car or the back of the car?

It's coming from the back of the engine.I check the cat with a hammer and there is no problem.This sound come really from the enginebottom.Weird problem.
I had before 10-40 and change last week to 5-30 Asyntho from kroonoil but this knock i had before oil change also.I remember from my supra91 7mgte that a big end knock that this noise stay and go more bad when i kick to 2500rpm and above but when i do this with my soarer after warmup then i can kick to 6500rpm without any strange noise and runs super.

i had a big end let go on me on my celica. and you could definitely here it. and it was constant. didn't come didn't go. was just a really loud rattle/knock and stuff all power.
the fact that it comes and goes i think would lean away from a spun bearing.
Hi guys, I take last weekend the engine off and checked yesterday de rodbearings and i find some worn/dammage rodbearings on cylinder 3 and 4 and rest looks fine.I go order this week a set rodbearings and put all on place and check again.If the problem is gone then i will write again.Thanks till now for all these reactions.
Hi guys, I put last weekend the new bearings and put all together and start the car and brrrrrrrr this noise is still there,only little more noise then before.I really don't know where i must look now or what i must check.I checked the rods and pistons without any play,so every help to put me in the good direction would be fine.
