Post 29: Crank it day

Post 29: Crank It Day!


At the end of my last post I was almost at crank it day but didn't quite make it and left the blog in the lurch.  Well the next opportunity came just a few days later and crank it I did!  Now I did take a video of it, to mark the occasion, while it was running and here it is although not the best.




Whilst congratulating ourselves I notice the pool of oil beneath the bell housing. . . . . a happy end to a long day then - don't think so.  Sleep on it and you never know the leak will go away wont it?? Er - No actually it wont.  Disappointing then as the engine didn't leak before so what have I done then??


I am confident that it wasn't the crank scroll seal but everything points to that so the engine had to come out again.

I am told by one of my suppliers to fit a lip seal to the rear of the crank regardless of what I find as it will leak!!  Well, after removing the flywheel I could not find any evidence at the back of the engine of any oil leak - really confusing as this wasn't just a drip!


At any rate I took the advice and went for the lip seal installation and purchased a kit.  The 1st stage of installation is to drill and tap the rear face of the block using the flywheel fixing holes in the crankshaft flange as a drilling guide.

Then we fit the seal and seal housings.

Next there was the cutting of the engine rear plate as the new seal housing is now in clash with it - an angle grinder is a wonderful tool and 20 minutes later I have the back plate cut and in place.

Then the flywheel and my home made clutch aligning tool get to work.

Lets hope that the modification works as I am told but still that niggling feeling that this isn't the oil leak but at least a good insurance policy if nothing else.


Whilst looking for the leak I came across another that I hadn't spotted.  It would seem that there is a blanking plate covering a hole in the block - this looks like a fuel lift pump hole to me yet there doesn't appear to be one on these engines - at least no gasket.  The Weetabix box took the hit and donated a gasket to the cause!

Crank it day 2 approaching fast, refit the engine and re-connect it.  Worth the wait and then, yes you guessed it oil leaking.  However, this time the leak is clear to see an it isn't from the crank, rather the oil gauge feed pipe connected to the engine.  This pipe was the original and is a shielded pipe and I think the rubber hose within had perished and cracked.  Not having access to a new part I have just made one.


Engine now running!
