Re: Die Garage der Schande
I'm sorry to admit that I've had a relapse. In my enthusiasm dismantling this engine I've got carried away and been placing cam covers, an air box, mfi system, and bags of nuts, bolts and other parts on top of everything else. https://uploads.tapatalk-cdn.com/20240420/8bf613e61b6f67c2eebe9759aabe775...

Re: Assessing an unknown engine
This one will not budge. Any suggestions are welcome, especially those known to work and not damage the engine.
For now, I'm leaving it with some penetrating oil to sink in.

Re: Assessing an unknown engine
I note the top two rings here spring out.
While the top two here seem stuck in their groove.

Re: Assessing an unknown engine
My curiosity has probably kept me going longer than I ought without having a tidy up. Everything is already going organised into freezer bags, but I'll probably go and sort some bench space for all the bits before going any further. I'm also starting to regret not cleaning the outside of the engine ...

Re: Assessing an unknown engine
The pistons look good to me, a bit of varnish or something on this one. https://uploads.tapatalk-cdn.com/20240420/ff31d57f38db4d0c8c47024c5a5a4b39.jpg And there's definitely some marking of some sort on this barrel. https://uploads.tapatalk-cdn.com/20240420/4a5262ba1ca61785fcec2ad83a912571.jpg I gue...

Re: Assessing an unknown engine
Dempsey says these chain guides are a single use item, but these appear to be brand new. https://uploads.tapatalk-cdn.com/20240420/0a28fb52c58599f88819e447c1bed098.jpg Judging by the nuts and some sealant around the rocker covers, I'm sure somebody's been in this engine during its 10 years of use. I...

Re: Assessing an unknown engine
This sprocket came away easily and I heeded Dempsey's warning to keep hold of the pin and not drop it into the engine. https://uploads.tapatalk-cdn.com/20240420/67b16958f0b58eadf6a70c82ef33a01b.jpg This sprocket came away easily https://uploads.tapatalk-cdn.com/20240420/5c3101c6f095fa65d700c611ab4b4...

Re: Assessing an unknown engine
To my mild amusement, I had a dream last night in which I was loosening a massive nut with enormous force and it suddenly yielded and turned easily. I've been getting quite demoralised these past couple of weeks at work, with some jobs building up and a number of customers getting frustrated with de...

Re: Porsche ranked least reliable car
Bear in mind this supposed "least reliable car make" counts among its metrics the cost of repairs, so to some degree it's simply a chart of the "most expensive car make". If you divided all the repair costs by the cars' retail prices, you'd get a new chart showing their actual re...

Re: Good usable 90mm pistons & cylinders wanted
Agree, that ^^^ is a much easier engine and risk-free Rob. I thought a '2.4' conversion to a 2.2 engine was a bit meccarno? Could be wrong, been a very long time since I thought about 2.4's as opposed to 3.2's. I think the Dempsey book goes through a lot of the common tune-up configurations? The bi...

Re: Assessing an unknown engine
If there is a chance Loctite has been used, heat up the big nut to release it. I’ve broken big sockets in the past when they should have been okay because loctite red made a big torque into a ridiculous torque, so i play it safe & warm the nut/bolt. Thanks for the heads up. Makes sense because ...

Re: Assessing an unknown engine
I’ve used a similar massive crows foot in the past with success. Can’t remember about the tensioner, but I guess that’s the way. Do you have the Dempsey book? Invaluable for this stuff Yes, I have Dempsey. My fear was the square drive breaking off the crows foot or cracking... the reality is, the a...

Re: Assessing an unknown engine
I had to get the orange 911 out to turn it around at the weekend, providing the perfect opportunity to bring the engine in behind the car and get it onto a stand. https://uploads.tapatalk-cdn.com/20240418/8564cb56e23f6893ebd464556f026c74.jpg A mechanic friend of mine vouched for automatic transmissi...

Re: Maddening Running Issue
A new pump after 50 years is probably a good investment even if the old one still works. (Just trying to make you feel better about it)

Re: Good usable 90mm pistons & cylinders wanted
. The 2.7 litre 911 engines have a stroke of 70.4mm so if using the 90mm pistons with a 66mm stroke, the swept volume - & hence the compression ratio - will be (significantly) lower. For instance, if using std 2.7RS pistons with a 66mm crank you'll end up with (from memory) a CR of ~ 7:1 Thus t...
