Priming Oil Pump following rebuild

[roadkill]

Hi,

looking at them online i can see how you could mess it up...... but yeah still.....

(assuming a composite gasket)
surely compressing it, and spraying it with hylomar (which should have been done) there will be bits and pieces of gasket and hylomar all over both surfaces. i dont mean machine them again, but scrape all the shit off, prepsol it and make it all 100% assembly clean again.

recently i tested my new head on the existing engine then pulled it off less than a month later, i still had to spend an hour prepping the head again before it went on the new short block.

working clean and general surface prep is the #1 thing when putting this stuff together (hence always having the air going)..... i spend more time cleaning than on tools when i build an engine, bhg job etc.

Hi,

i think you'd be safe to not have to do much to either surface as the gasket was never heated and engine ran so it won't have done it's job. Obviously though have a good look over both faces to make sure there is nothing still stuck on.

BTW - how the smeg did you put the HG on the wrong way?

Cause i'm a tard??? LOL

The really bad part, i distinctly remember flipping it over because i 'put it on the wrong way' the first time....woops

Wheres the oil pressure switch take off on these motors ?? .. Did you ever run it crank / it with the oil filter off & if so did any oil come out ...

Hi,

i googled what a 3s head gastket looks like. Could be fairly easy to do compared to others......

Off the cylinder head.

I did crank it with the turbo oil feed off, and yes oil did come out.

just be thankful it wasnt anything more serious

This thread needs a face-palm pic :-)

Glad you found the problem.

I've taken note of the things I should've done when assembling my engine, but didn't. Like turning it over to build oil pressure without firing it up. But I did use a 2nd hand pre-assembled bottom end, not new bits.
And I'm really glad that mine worked straight away despite the mixing of the Gen 3 & Gen 4 bits.

THat's awesome news Roundy, at least you can progress from here, and stop ripping your hair out

Facepalm is much cheaper than engine removal.

Fwiw, I always smear a thin film of goop around the oil feed hole on the gasket - helps remind you to place the gasket correctly over the oil supply hole on the block.
