engine thumping

[87mgte]

i think its rod knock(but the engine only have 155k miles). when the car is running if u put ur head under the car or low to the ground u can really hear something hitting the oil pan or something in that area.

If you think something's hitting the oil pan and don't think it's the harmonic balancer being loose, don't run it anymore and start on the swap...

were pulling the motor tomorrow,also we order a 7mgte and it should be here but next week sometime.

i would check the torque on the balancer bolt first before pulling the engine. a loose bolt does sound like a thump way low down on the engine.

Is it the V6 version or the Inline one?

i have a N/A 87 3.0l v6 and the engine is making a thumping sound(like something is hitting against something)

any ideals?

DERRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!!!!!!!!!

OK, kids, the V6 joke is played out. Let's drop it...

gamer565, Supra's have an inline 6, not a V6...

Sorry, i've recently had to deal with some V6 supras lately.

yes i know now, but at the time when i was talking to the owner over the phone he told me v6. but now that i have the car in my drive way its a inline 6 getting replace with a inline single turbo 7mgte.


and the only reason were going with a 7mgte is cuz 1 its cheaper and 2 less modifying.

I'm some what doubtful that this is rod knock, the thumping sound the original poster is describing has all the hallmarks of a loose harmonic balancer/Crank Pulley bolt...

There is usually an automatic assumption here that if it's a 7M and it's knocking, it's rod knock. You have nothing to loose by having a go and re tightening the bolt.

And by the way, re-tightening that bolt is not something you are going to do with a 3/8" drive ratchet.

It requires 195 ft/lbs:

even if it is or isnt....the motor is getting pulled tomorrow or wednesday, then when the GTE gets here its going in and once we get that all done ill look at the 7mge sometime and see exactly wats wrongs.

Hmm put big magnets on back bumper and keep driving it eventually bad part will fall out and the magnet will catch it and you can fix it when you get home.

That would have saved me some time when a rod "fell" out of my old 7M.:3d_frown:
