PanamaZ34 Posted January 18, 2010 Report Share Posted January 18, 2010 Sorry, been a while since I had to ask a stupid question, so I reckon I can impose on everyone with one The rear cylinder head on my Z34 is now loose, but is still held in place by the timing-belt back-plate. The timing-belt tensioner pulley seems to be connected to the end of the head, and if there is a way to remove it, it isn't obvious (Haynes mentions a "bolt at 10 o'clock" that needs to be loosened, but I can't see anything)! I suspect there is a blindingly-obvious answer (I spent hours wrestling with the cam-carrier until I realised that removing the power steering reservoir would allow the bracket preventing it from lifting off to be hinged forward out of the way)! Is there some way of removing the pulley that I haven't discovered yet, is it just a case of wrestling it off (hopefully without damaging any of the flanges on the underside) or is there a obvious answer that I'm too thick to have spotted?

Crazy K Posted January 18, 2010 Report Share Posted January 18, 2010 why are you removing it? Quote Link to comment Share on other sites More sharing options...
White93z34 Posted January 18, 2010 Report Share Posted January 18, 2010 should be a torx50 to remove the timing belt tensioner pulleys Quote Link to comment Share on other sites More sharing options...
PanamaZ34 Posted January 18, 2010 Author Report Share Posted January 18, 2010 The gasket has gone, but given how much needed doing, I would probably be doing a full top-end rebuild anyway (to hopefully save on future grief) Quote Link to comment Share on other sites More sharing options...
PanamaZ34 Posted January 18, 2010 Author Report Share Posted January 18, 2010 should be a torx50 to remove the timing belt tensioner pulleys Bingo ........ once you know what to look for, a rusty hole becomes a lot more! Now all I need to do is get myself a better screwdriver set, so I can get at it! Thanks Chris Quote Link to comment Share on other sites More sharing options...
Octavarium454 Posted January 19, 2010 Report Share Posted January 19, 2010 Make sure you replace your oil pump distributor o-ring while you have extremely easy access to it. Quote Link to comment Share on other sites More sharing options...
spiderw31 Posted January 19, 2010 Report Share Posted January 19, 2010 Make sure you replace your oil pump distributor o-ring while you have extremely easy access to it. x2!!! If your alternator is questionable, now is the time to take care of it as well. With the rear head and manifold off, the alt can be pulled out the top without too much trouble.

Crazy K Posted January 19, 2010 Report Share Posted January 19, 2010 make sure you do a quality job on the o-ring. use a quality brown silicone rubber seal, and a paper o-ring. Quote Link to comment Share on other sites More sharing options...
PanamaZ34 Posted January 20, 2010 Author Report Share Posted January 20, 2010 Already replaced the alternator (the subject of my first batch of stupid questions!) ....... before I realised I was going to have to do all of this! I got a replacement O-ring along as well as the gasket set, only thing I think I still need (after having the heads skimmed and the new manifold studs fitted) are replacement head bolts, but they should be easy to get here. Then it's just a case of trying to remember how everything goes back together (and the order!) and having the timing done. Who knows, with any luck it might even be back on the road this year!
