Re: Assessing an unknown engine

There’s no (visible) scoring on the bores from that damage? Difficult to see from the photos, but is the top of the piston clean or is it some deposit build ups that then look like damage? There's something there but I'd say it's more subtle corrosion. I think there is the slightest hint of a score...

Re: Assessing an unknown engine

So that just leaves one cylinder on the engine, on the other side. Gently turning the crankshaft I was able to confirm it's this cylinder restricting the movement of the crank. I guess I'll add some more fluid and save that battle for another day. https://uploads.tapatalk-cdn.com/20240421/499e5856d6...

Re: Assessing an unknown engine

After making room for some of the parts, I turned the engine over today and removed the other rocker assembly. The left side of the engine tells a different story. These must have been the problems seen on the scope. Two pistons are broken where the exhaust valve cutout meets the barrel. With both c...

Re: Die Garage der Schande

Amazing what you can find hiding away in a cluttered garage. The chipboard I thought I had was nowhere to be found, but finding this 8x4 sheet of ply tucked behind the racking was a surprise. https://uploads.tapatalk-cdn.com/20240421/d7ec47258434d9972de1ae131132a8c6.jpg New shelf finished https://up...

Re: Die Garage der Schande

This shelf will be made entirely out of bits and bobs I kept because they might be useful one day - joist offcuts, some spare hangers, a nail gun I wasn't sure I'd ever use again... I'm taking this as vindicating my hoarding habits. Batten the opposite side and some joists across: https://uploads.ta...

About £2000 should cover it.
"Never again" I'm pretty sure you said last time. [emoji3]

Anyway, I think you should twin plug that one too.

Have you got an MAF on there? If so, what injection system?

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.
