Is it really possible that after only managing the measly 87bhp out of my 1600 astra on the rollers yesterday, that the gearbox could cause this? only for a while one of the bearings has been noisy, after yesterday's drive to interpro that noise has gotten far worse not is it only rough but also knocky.
I'm wandering would this have caused the lower than i had ever expected output?
Tourqe curve was excellent, operater said it could do with having the air correction jet changed to slighty larger, but only made 87bhp, standard bhp is 82bhp on the 16sv, in fact John's nova sr made 82bhp (1.4 webber carb and filter) whereas i have 1.6 webber 32/34 carb, P/X air filter-breather, Sportek system from downpipe back,
Also i'm aware that the valve seals are leakin oil on overun etc as after going downhill and then driving as normal it tends to smoke.
Sorry so long thoughts please.
