this car has got me worried now, this

morning i started the car & the lifter noise was thr as

usual, i thn decide to drive it around the block

but the noise jst stayed thr & was accompanied

by a grrrrrrrr sound as i accelerated, the oil light

also flashed about 3 times, bck @ home i idled

the motor & the noise was very loud on top at

cyl 1 & when i rev it, i gt the grrrr sound. i

removed the lifters & cyl 1 lifters were totally

hard 2 depress, bt my wrry is the grrrr sound

when reving lightly... could faulty hydraulic lifter have caused me to spin a rod bearing

Hi mate, doesn't sound good that i'm afraid mate, those grrrrr sounds are the worst of them lot

I wouldn't want to even run the engine until you've at least whipped the sump off and had a good inspection down the bottom end, I've never heard of a faulty lifter causing t o spin a bearing before, tell me off for teaching you to suck eggs, but have you checked the oil level?

The oil level is 100 percent mate...

Whats the oil quality like? last time it was changed? the filter too.

As pete says I would drop the oil and have a look at the bottom end. Might be worth having a look at the chain tensioners too, not the stereotypical sound that chains make but you never know.

I'm thinking possibly oil-pump perhaps if your oil light was flashing ? Is oil getting to the top of the head ?

Could well be, I have heard when oil pressure starts to drop then cylinder 1 is the first to stop getting oil, due to the way the head is angled.
