Ok I have a “messing with my head” problem!
Recently re-registered my 32gtr after a few years. Changed all fluids and replaced engine and gearbox mounts. Really don’t know how long passenger mount was broken for.
I now feel a vibration in the seat when hitting 0.3 bar boost and get worse as boost build / power increases.
Now this problem only happens when the car is warm/hot.
I.e after brief warm up it will drive for 10 or so minutes beautifully under boost / strong acceleration.
Then after a while vibrates under boost.
- I have run in rwd by removing the fuse and problem is still there.
- recently had new tyres balance and alignment which was fine. Same mechanic inspected centre bearing and said looks fine.
Mechanic also couldn’t feel the problem as does not start to happen until after driving for a while.
-engine and steering are smooth. Engine knock always low under 30.
vibration is not speed sensitive as all speeds highway etc are smooth under 0.3 bar.
The problem feels like it’s coming from / sending vibration to rear left.
I see my rear turbo is leaking.
there is no bearing / turbo whine. However under high boost 1 bar I can hear a fast fluttering sound.
Could a bad turbo cause a vibration felt in the seat?
Any help is much appreciated.
