Hi guys Just wondering if you have some ideas for me: Symptoms are: whining, whirring both reasonably loud with a cold engine. It increases with acceleration, decrease with your foot off the accelerator, and goes away completely once the car is warm, say 2-3km. It seems to come from near the belts on the left side of the car facing the engine. Regards, Simon

Bearing in the power steering pump or air con pump? It's been a while, but if I recall correctly they are both on the front left when facing the engine on an sr18.

If it will make the noise when standing still I'd be removing both the drive belts and running it briefly and seeing if the noise goes away, this is a bit difficult without getting it on a hoist. If it persists you may have an internal sludge problem which is causing the oil pump to whine while the oil is thicker when cold, and upsetting flow to the chain tensioner and cams, seen this plenty of times on SR's. This is an expensive repair.

What he says ^^^^^^ The other part of the issue is sludged up cam oil bars.Ie the oil spray onto the cams is restricted.

Hmm, that could possibly be a roller rocker head, not 100% sure if the SR18 got them at the same time as the SR20. The roller rocker doesnt have cam oiling bars and sprays from below, they dont suffer the same oiling issues like the early ones, but any badly neglected engine could do it.
A quick check of the timing chain & tensioner by removing the rocker cover could answer the question.
