Subject: Re: LG6 LG45 valve / ignition timing marks
Thought I'd read through the factory handbook thoroughly. Now I see it states that the flywheel pictured on page 28 has an IVO marking at 5 degrees. It comes down to semantics. One would infer that that is correct for the LG6 one has just bought...but no, it really does mean those are the marks shown in the picture!
Hidden in the text a couple of paragraphs lower, it actually states that IVO is in fact 8 degrees. Relieved as that is close to my estimate for my flywheel markings. I've now reset my tappets which brings openings closer to that setting. But I daresay I'm not the only one to have altered their camshaft sprocket setting to the 5 degree setting. Having last driven the car 16 years ago and only just got it back on the road, I'm not inclined to engage in the major dismantling involved in resetting it...especially as I will probably have major work done on the engine sooner rather than later.
This still leaves the mystery of the offset from centre line clearly scribed/stamped on the side of the hole for viewing the timing marks. This is surely intended as a timing mark, so why is it not central, in line with the crankshaft?
