Pegasus Racing has the plastic gauge.

Nice to see people actually checking specs when there building motors.

[DrLeadFoot]

I'm just terrified that I'm going to blow this up so I need to do it the right way.

[ClassE]

Plastidipping the crank was an odd choice.

Racekor.

People usually don't clean journal bearing seats or install the bearings right 90% of builds gone wrong. Spun bearings are bad news

[DrLeadFoot]

I think I did it right. Tried to keep everything as clean as possible. Rubber gloves and brake clean were flying everywhere!

[GunMetalGrey]

What is all the white stuff that you have on the main bearings and caps? Assembly lube of sorts?

Are you replacing the crank sprocket? You had mentioned that it was rounded.

Looking good!

Assembly Lube

My project of the weekend is to get the new sprocket on.

[DrLeadFoot]

These two inverted torx bolts that secure the lower cover on were finger loose. No wonder I was leaking oil.

Another nice find by the doctor!

[DrLeadFoot]

Jesus bolt out.

Stretched as I thought. If you didn't read it earlier the bolt was easily loosened by a big pair of channel grips.

[DrLeadFoot]

Any advise to get the middle torx bolt on the timing case cover loose without removing the cams?

[jc43089]

You might have to remove the short chain and tensioner but not the cams.  Try a 1/4" drive 12pt socket and swivel.

[DrLeadFoot]

Still trying to find time and motivation to get in the garage. 

I was thinking about not using the metal gasket on the front cover and just going for the Ford black atv sealant.  In order for Kummrow to stop the leaking I had to ask them to ATV seal all gaskets. 

I will be ordering new exhaust vanos sprocket bolts just in case the old ones are stretched out like every other bolt has been so far. 

That should be it for parts then I just have to get my ass in gear!!

[jc43089]

What is your crankcase vented to?  I'm just curious because I have never had leaking problems like this.  If your crankcase gets pressurized though it will leak everywhere.

[DrLeadFoot]

I have it on vacuum via the exhaust.

Have you turbo'd one before?  I guess they leak pretty bad from the crank case pressure.

[jc43089]

Vacuum via the exhaust?  Not sure what you mean.  I have not had a turbo before but these engines have a large vent so i would think unless you have lots of ring leakage it should vent fast enough.

[jc43089]

So it isn't a vacuum, just a low pressure, it attaches post turbo right?  There will still be some pressure.  I am not sold on this setup.  Why not just a catch can vented to atmosphere?  I understand that you don't want oil going into the turbo inlet so this would be the next best thing.
