DuRRk

hello, Indeed I posted this a while ago, but I'm just new on the forum, I could find my message back I got a helpfull email from Paul from v8tuner.co.uk. He told it does happen more often with these v8's: 'The Rover engine is typically a little noisy when starting from cold due to some loss of oil from the lifter due in part to the pressure on the lifter from the pushrod and some oil leakage from the internal lifter mechanism" It could also be some kind of dirt: ""In some cases lifter noises can be due to oil contamination. We have inspected Standard, Crane and Rhoads lifters and have found old and low mileage lifters to contain various debris such as grit, swarf, oil sludge, additives etc etc" I did change the oil after the first 100kms with the new camshaft. Perhaps I should change the oil again? I think I'll just drive along for a while, see what will hapen to the noise. I also got the advice from Paul to idle the engine for a few minutes before driving off. I'll try and locate the noise, see if I can locate the cylinderbank. thanks for your replies, Durk

thanks for the reactions everyone. I think I'll stick to the same oil, I could perhaps put new oil in the engine, I'll drive along for a while to see whats happening with the noise DuRRk

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

I recently fitt a new crower 'torque' camshaft with 'rhoads bleed-down' lifters, results where amazing, a whole lot of extra torque low down! Now recently the engine ticks a little, only on the cold start, and its difficult to hear, it looks like the lifters have to fill up with oil again. Is this sounding familliar to others? Do others have experiences with the 'rhoads bleed down' lifters? http://www.v8tuner.co.uk/ It doesn't look too harmfull to me, or should I change the oil type? I use 15 W40 mineral oil now, it is should be a perfect oil for the engine according to the books. anyone ideas or tips? thanx, Durk Range Rover V8 high compression 9:35:1, 2 strombergs, on lpg
