Hi lads looking at doing some work to the supra and so did a compression test today to check it’s health. So at the minute I’m pretty sure the vss are fooked and the turbo seals to after driving it in the summer last year. So here are the results, I’ve had her running at bpu for about 2-3 years now at 1.4 bar not all the time mostly 1.2bar. Ah and she has about 160k on the clock still pulls like a train apart from the odd puff of smoke on idle at traffic lights after a good push. And a little on start up in the mornings.
Warmed the car for about 25 mins to running temp, took the 2 30 amp fuses out. One spark plug at a time starting from front to back and these were the readings
From front to back
1 151
2 156
3 156
4 154
5 153
6 152
Also this was throttle body fully open. Does it matter that I left the other spark plugs in as I read this was the way and now I’ve seen you should take all 6 out ??
Thanks lads
