i've read that before, but defiantly a good read. i'm expecting strange readings as it's a tight engine to start with. With time, it should be normal readings. this is why i fit the pressure gauge.

pleased to say that i have resolved the heavy white smoke from the engine. Upon strip down and further investigation, i found the following inlet port.JPG oil in pcv.JPG so the PCV valve was sucking oil from the crankcase and then going straight into the cylinder. I have binned the idea of a PCV val...

yesterday i fitted new seals to the alloy timing cover after the old ones blew with 100psi oil pressure. I thought you said that some dumbo had fitted the oil seal AAF (abbreviation of back to front)? Re the oil pressure: There may well have been extra restriction of oil flow if you stuffed everyth...

i have a hif44 carb fitted to a mini spares water heated manifold. it does have a crankcase breather connection, but i have that blanked off

so yesterday i fitted new seals to the alloy timing cover after the old ones blew with 100psi oil pressure. on the subject of that, i managed to removed the pressure relief valve and you would expect it to come out rather easy, well sort of. i replaced it with another i had and it went in smoother. ...

One thing I can confirm is the reason why the alloy timing cover has leaked, is it has come from the oil seal. The supplier had it fitted the wrong way around. I didn't notice this when first fitting, error on my part. I've replaced it and fitted it correctly now. Wire rope seal facing the oil throw...

I'd agree. It's the same dipstick that came with the engine. I have the plastic holder as well.

What makes you ask that? Too much oil?

Moss catalogue lists 1098 and 1275 as the same part number. 12G175. I just looked.

I think the reason it failed was probably the crankcase pressure/oil pressure. I've purchased a new seal set which arrived today. It was a heavy leak at the bottom. I'll renew the circular oil seal as well.

Ok, I've removed the inlet manifold and there is oil in it. Also oil in the cylinder head inlet ports. My theory is the pcv valve is sucking oil from timing cover and sending it straight to the inlet manifold. This is going into the cylinder bore and that's why I have white smoke. I'm also thinking ...

i looked at this a while back. Mercedes Benz eh!

yes it was the electrode. this week (if i find the time) i will strip the engine and report what i find. my main concearn is the high oil pressure at the start and what damage it has done. before i switched it off, it was idling at 30psi. So maybe a blockage that has cleared itself? I did use Grapho...

I think that's the easy issue. I dont know if that's the cause of the white smoke.

My plan is to remove the manifold this week to see which cylinder the oil is coming from and then remove the head. Hopefully that might give me an answer

Oil pressure gauge was connected to the 1098 I removed so it was working correctly. The 1098 used to show 60psi on start up

It was the standard 1275 one. When I get a chance this week, I'll check it and its length.

When the engine had warmed fully, it was showing at 30psi so I dont think it's an issue now. I'll still check.

Have a look at the oil pressure relief valve. the oil pressure should never be over about 65 psi. Also, if you had it rebored, did you clean out the oilways? yes. I had the plugs removed and had NPT plugs fitted. I cleaned the oilways with gun cleaner then compressed air. I did this around 6 times....

i had the block relined back to standard 70.61mm. the bores were honed. There are new pistons and rings fitted also. i would agree that blue smoke would be rings. But this is white smoke that smells like oil. It's rather bad. excessive crankcase pressure? Would the PCV not help that? There was a sma...

i am after so advice as i am unsure of where to look next. i rebuilt my 1275 back over the winter. I ran it for the 1st time yesterday. I used graphite build paste on the rebuild. When i first did an oil pressure check on the engine with the plugs out, I span the engine over on the starter to circul...

I have the rubber seals from moss fitted to my 1275. I have the engine finally in the car but not running yet. They were a very good fit.

i purchased another MC cap and modified it.

tool for life!
