Re: Assessing an unknown engine
The magnesium stacks and throttle bodies have blooms of corrosion in all the nooks and crannies, including inside. https://uploads.tapatalk-cdn.com/20240602/4137ab423114d9d8f882c0699053a807.jpg It would have been a lot of work to abrade it all off so I tried using some ferric chloride to turn it int...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod
Great news. The reason the screw was stopping (but still turns) is because the nut around it has come back into contact with the rocker again. If you back the nut off a bit more, you get a better feel of whether you're incontact with the valve/cam.

Re: Assessing an unknown engine
In preparation for removing the exhaust studs, I was watching a couple of videos as you do, when I saw one of these contraptions. https://uploads.tapatalk-cdn.com/20240601/b4e3940f85ccf210c61d2c01729f113d.jpg It turns out I have a couple in a lovely old Britool tool set. I'd been wondering what they...

Re: Assessing an unknown engine
I think the engine rebuild kits from Design 911 also have new guides, but you need to check that Rob. Fresh guide bores may well close things up enough to have a reasonable clearance. Thanks for the suggestion Graham. Sadly it doesn't look like they do the kit for this engine, only the later ones. ...

Re: Assessing an unknown engine
I finished measuring up tonight. I read it's the exhaust valves that always need replacing because they wear twice as fast. All the exhaust valves are bigger than the minimum wear spec of 8.928mm, albeit only just above. Whereas all but one of the intake valves are worn outside the wear spec of 8.94...

Re: Assessing an unknown engine
I found half an hour's worth of midnight oil to burn measuring valves yesterday evening. https://uploads.tapatalk-cdn.com/20240530/2ea9ab5a54b2a33a89991f1cf1c080ec.jpg https://uploads.tapatalk-cdn.com/20240530/eb436e85ecefb87bc327c70003078655.jpg All may yet be discarded, depending on measurements, ...

Re: Road Tripping to the Pyrenees
Great trip and thanks for the read. I'd love to do this some time.
Sorry about your mechanical woes Gary. At least you have an excuse to do another trip, now.

Re: A Dream Fulfilled - MY 904FF
Some of you might have wondered what had happened to the "FF" over the last couple of years. It has obviously been hors de combat due to Jim's "off" at Shelsley Walsh in 2022. The good news is that an improved version - MK16B!!? will be at Shelsley this weekend and its more dila...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod
ATM I'm fully expecting the cylinder 2 intake tappet to be half a centimetre too far open! Do you recall slacking any off more than you might have expected, when adjusting them?

Re: Assessing an unknown engine
I realised I can cut the outer 30 degree and the inner 60 degree faces regardless of whether any valve guides will be replaced. Only the actual mating face grind, made with the valve itself, needs to be made in the final guide. https://uploads.tapatalk-cdn.com/20240527/9ee5e8ed72055d6cebcd554635fe42...

Re: Assessing an unknown engine
Five of the head gasket faces are good. https://uploads.tapatalk-cdn.com/20240527/14d2d1e8508b2d1d71dc9c8a3e87e5bb.jpg One has some pitting where it was corroded at the gasket, so I guess they all need a quarter mm off. https://uploads.tapatalk-cdn.com/20240527/654e2fb59acba4babb6b51c54c3b331f.jpg S...

Re: Assessing an unknown engine
I made a seat cutting tool for the 30 degree slope and picked a valve which was representative of the others. https://uploads.tapatalk-cdn.com/20240527/9f132084ad9ad9a821653687eb13769d.jpg In my garage sharpie serves for the blue stuff I've seen proper engineers use. https://uploads.tapatalk-cdn.com...

Re: Can you guess what it is yet?
and WHO would have a 50mm drill in the garage!? When he retired from cabinet making, my granddad owned a hardware store. I was too young to remember it, but I think it was one of those places with ladders, no room to move, and shelves upon shelves, where you could find absolutely anything. I think ...
