Thanks Erroll I only run mobil 1 and change at at least 4-5000km or before each
race meet. Since changing its as quite as a mouse again:) My catch can had a
fair amount of oil in it I would say 20psi and a lot of revs from teh street
machine show a few weeks ago migth have degraded and used a fair bit. I like the
sound of the solid lifter and cams option but wouldnt they be a bastard to
setup??and also be pretty expensive I wouldnt mind a bit more power up top what
kind or revs do you think the cams ect would increase maximum power too??? at
moment its around 6500rpm.
Thanks again Andrew
