Hi guys, as some of you know I've bought a donor 164 12v Cloverleaf that's had some work done to the engine and box with the intention of just doing a straight swap whilst the current engine and box are out and the chassis is being repaired. Unfortunately the engine is burning a significant about of oil, it's getting into the inlet tract via the oil breather and pipe to the throttle body rubber elbow. I'm assuming that the crankcase must be getting pressurised to cause this much loss.

I've cleaned out the breather tank attached to the back of the plenum and swapped it for a second known good one, pipes are all clear too. I've just done a compression test on the engine and had 155psi on cylinders 1, 2, 3 and 130psi on 4, 5 and 6. I'm coming to the conclusion that there are issues with the rings on the front bank.

What sort of compression are other people seeing on their engines? And if anyone needs to borrow a tester in the future just let me know!

So, does anyone have any bright ideas? The engine and box are coming out of the donor tomorrow/Monday so I probably won't be able to run it again until it goes into the Stratos at some point in the future.

Does anyone have a good source for 164 12v gasket sets too? I'll probably need one soon and a spare sump gasket. There's a brand new pan to go on the engine once I've had a boss welded onto it to take an oil temperature sender!

Cheers
Guy
