Sizes needed? Don't just say "everything" cause that'll be heavy=expensive.

USPS small flat rate box is anything up to 70lbs. And it would probably be there in a day and a half.

Let me double check. Going to check brgracer's reroute thread real quick. Cant remember the thread pitch of the coolant sensor or what size heater outlet I need. I think just 3/8 would be fine.

Edit: confirmed, need the 3/8 NPT tap and the bit that goes with it. Do you happen to have a M12x1.5 tap for the sensor? A friend of mine locally probably has it but i'm not certain he has anything larger than 10mm.

curly 05-21-2010 03:43 PM

Well let ME double check what I have. Brb.

Edit: Ok, I have 37/64 drill and the 3/8NPT tap to go with it, but only M12x1.25. My drill chart doesn't even show M12x1.5, only 1.25 and 1.75. I thought I did since I drilled and tapped my spacer for the sensor, but I must of left that out of my box when I quit, cause it doesn't seem to be there now...

wayne_curr 05-21-2010 03:56 PM

Hmmm interesting. I'll check my buddy's shop and see if he has the 12x1.5.

Go ahead and send the rest of it! Doesn't have to be anything special, flat rate might not be the cheapest way. Any way you ship it it will be here overnight i'm pretty sure.

Engine is in but it smokes pretty bad when I roll into boost. :( :( :(

Try ditching the PCV system if you haven't already.

I just have a filter on the hot side and a GTX Valve on the cold side. I'm fearing the worst, its a lot more than just a little. Its a substantial amount of smoke and it wasn't doing this with my last engine.

Ditch the pcv, hook both ends to a catch can. Does that block have a port with a cap down near the oil filter?

And you didn't call me. We're over!

I know i know, i'm just sitting down to write you a PM!

Anyway, I got called into work so I couldn't do any more troubleshooting (also my excuse for not calling you ;) but right before I took off for work I coudn't resist taking it for another spin around the block. No smoke this time, but it wasn't immediately obvious last time either, it took a little bit of driving it around before I noticed it.

Anyway, now I have a horrible leak between the mani and head so I have to get this bitch resurfaced for sure. I'm just affraid that its not resurfacable which will mean I have to weld on a new flange which means even more downtime. How are the exhaust mani gaskets suppose to go on? Does the flat side go toward the head or does the embossed side go toward the head? I might have installed it wrong.

Edit: No, this doesn't have the block port.

Embossed side out, facing the manifold.

Ok I got it right then. Thats what I thought.

wayne_curr 06-09-2010 03:35 PM

Went for another drive this morning. Looks to be happening mostly under decel. Seems like vacuum pulls oil into the combustion chamber, then when i stab the throttle it puffs smoke like crazy. I dont see any smoke in my mirrors while i'm accelerating in boost although I cant pay much attention since this thing accelerates pretty quick at 14psi.

Other than the oil smoke and the leak at the manifold, its running as well if not better than ever.

Either blow turbo seals, or valve stem seals most likely.

I'm not sure which is more likely but i'm going to go pull a charge pipe and see whats up. If there isn't any oil in the charge pipe i'm going to assume valve stem seals. There is definitely oil between the head and manifold where its leaking.

wayne_curr 06-09-2010 06:03 PM

More news. Charge pipes are clean, its not the turbo. Its the rings in number 3. The spark plug is covered in oil. It is blowing oil out of the breather filter on the driver side valve cover so i'm definitely pressurizing the crank case badly.

Damit that is the same thing that is happening to my GTX right now, same cylinder. Honistly I never saw that engine run I assumed it was good the cylider walls looked good and the tops of the pistons looked fine.

I just hope it isn't ringlands. If it were ringlands, the cylinder walls would be scored horribly wouldn't they?

No guarantees that it would.

Before I throw out my crazy idea...how long did this motor sit before you got it?

No idea. Probably many years in the back of bob's garage. I hope your crazy idea has something to do with getting rings unstuck from the piston after sitting a long time. I tried soaking the piston in ATF overnight but that hasn't helped :(
