Hello,
In March or April this year I ordered a Crower Comp-U Pro 50299 Kit at www.v8tuner.co.uk, with Rover V8 Rhoads Bleed-Down Lifters. I installed everything and follow the procedure to first get oil pressure, then idle the engine for 20 minutes at several different revs, not to high, but certainly not idle, around 1500 until 2500 revs.
Everything went fine, the engine runs beautifully, and i got really nice torque driving from standstill with the automatic gearbox! I lareaddy drove a few thousand km's.
Now, when the weather is getting a little colder, one cam follower starts to tick a little bit, only when cold, only when I drive, so when there's little load on the engine. I drive very gentle on a cold engine. When I first start the engine in the morning, I cannot hear it, as soon as I start to drive, even very slowly, I hear it.
I know the sound of cam followers very well, as I just had the problems with the camfollowers before ;-)
I thought: Is it logical due to the 'bleed down'effect of the cam followers that it ticks a little on cold engine? I use 15w40 mineral oil. Should I use a thinner oil like 10w 40 or even thinner?
Or is the ticking noise not normal at all?
Does anyone have experience with the type of lifters I use?
further specs:
Range Rover
9:35:1 compression, 2 strombergs, lpg
zf4 hp22 automatic gearbox
I always start on lpg, without any problems
thanks in advance,
Durk
