bad idea or terrible idea?
 

in my never-ending quest to vent crank case gasses, this is what I have done: Drilled a hole in the side of the block, and attached a -10 AN line to the side of the block, this will go to a huge catch-can. Results after the first drive.

Re: bad idea or terrible idea?
 

I'm really leaning twards terrible idea.. only because I would never drill into the block, I would think that it would make it weaker and give way under pressure

Re: bad idea or terrible idea?
 

....It...might.work....??..

Re: bad idea or terrible idea?
 

Good god kid... Where the hell do you come up with all these crazy ass ideas?? Massive drug influence?

Re: bad idea or terrible idea?
 

If you post it I assume straight away its a bad idea. How about fixing the rings that are shot in your motor to eliminate some crank case pressure, or just buy a real vacuum pump?

Re: bad idea or terrible idea?
 

The real fix!

Re: bad idea or terrible idea?
 

Well it looks like its already leaking. and wouldnt this spit a lot of oil into the catchcan. Man how pissed are you going to be if that messes up your block

Re: bad idea or terrible idea?
 

the hole i drilled was in the balance shaft chamber, it was very thin, only about 3mm thick. the drips are weatherstripping adheasive.

On my buddy's turbo ford, there is a hole drilled in the aux shaft chamber similiar to where i drilled it on the 4g63. The turbo ford motor guy never has had a valve cover leak, and wonders why 4g63's dont have a crank case vent, only the head pressure relief vents.

should be installing the engine tonight!

Re: bad idea or terrible idea?
 

judging by the idea and picture, terrible

Re: bad idea or terrible idea?
 

na, probably just the massive amount of undiagnosed PTSD that i got back in 'raq

Re: bad idea or terrible idea?
 

well, this engine was just rebuilt .20 over all machine work done by john gosh, rings staggered properly and last time we did a compression test, it was 200 across the board, your call

Re: bad idea or terrible idea?
 

What symptoms are you seeing that are making you do all of this?

Our crankcase vents out the valve cover ports. If you have quite a bit of excess pressure, why not just add a second fitting to the valve cover like has been done time and time again? Or like has been mentioned, just hook up an actual vacuum pump.

Re: bad idea or terrible idea?
 

I'm convinced that iceminion and Tom chat late at night and come up with these things and give eachother advice in general.

Re: bad idea or terrible idea?
 

Wow.. im not sure what to say. You must be bored and like to waste money.

Re: bad idea or terrible idea?
 

Wow, I am voting terrible idea.
Where is the vote button?

Re: bad idea or terrible idea?
 

If you have good compression, why would you waste your time with this? There's a good chance your block will just crack around it, and in the end it really accomplishes nothing.

Good work though, come find me at the cookout and show me this mod, I want to pat you on the back for most-amazing-silly-overkill-pointless-but-well-attempted-and-humorously-executed-mod ever :)

Are those lines from Slowboy Racing? :P

Re: bad idea or terrible idea?
 

the engine was rebuilt, and then was used in my brother's laser which put down an estimated 350 whp (not bragging, just it was pushing some serious HP)

he was constantly plagued by oil leaking over everything, we tried every trick in the book to stop the oil seeping out of the top end, to no avail.

My brother decided to quit while he was ahead, parted his car, and bought a 2g. I grabbed his motor.

So, all I am doing is applying a feature common on other turbocharded cars.

I drilled the hold in a non-structeral location on the side of the block, I didnt drill through any major "webbing" in the casting.

Re: bad idea or terrible idea?
 

200psi of compression? Is it all-motor?

Re: bad idea or terrible idea?
 

we put 2G pistons in it, i think our compression tester is reading a little high honestly, but its pretty even across +-5 on the gauge.

Oh, and one more thing, before I did this, I asked John Gosh about drilling a hole in the block, i pointed to where I was going to drill it, and he thought it was a great idea.

Basically if John Gosh not only agrees with me, but calls it a good idea, im not really worried.

what I am worried about is still leaking oil after all of this. then I will have wasted my time with this mod.

Re: bad idea or terrible idea?
 

DAMN YOU!! While reading this i was telling myself "do not draw attention to yourself and perhaps they group you with him." Then Matt had to go and talk shit. Like always...

Re: bad idea or terrible idea?
 

350 is not Serious HP, esp. today.
and the oil leaking could likely be fixed by sealing the individual leaks, or building the motor properly. Whenever i had a problem with the oil leaking out the vc, its always been either the valve cover is cracked, or the gasket is shot. Get a new rubber gasket and call it a day.

Re: bad idea or terrible idea?
 

I think something to draw the air out would be better, but letting the air out easier shouldn't hurt.

The REAL question is, why was it leaking oil everywhere? There are 1000's (maybe millions?) of other 4g63's that didn't need this mod to not leak oil all over.

Re: bad idea or terrible idea?
 

I don't think it's a horrible idea? Won't this really really relieve crank case pressure? Assuming it doesnt leak, I'm sure there might be standing oil in the line? I guess I just imagine oil being forced out of there, but then again it doesn't "normally" shoot out of our dipstick lol.

Re: bad idea or terrible idea?
 

Why put the block's integrity into question when adding a larger pipe in the valve cover would suffice?

Re: bad idea or terrible idea?
 

sad thing is its to late

Re: bad idea or terrible idea?
 

This is going on my rebuild for sure!

Re: bad idea or terrible idea?
 

There is you answer. If you are worried about it why would you do it in the first plac???e

Re: bad idea or terrible idea?
 

:pc:

Just let us know if it work. I if it has been done on other turbo charged engines in a similar manor, it might work. I have heard of this mod on the ford block also.

It is done already now just wait and see the results

Re: bad idea or terrible idea?
 

Done yet?
Work or not i will stay with the bigger holes in the valve cover mod.

Re: bad idea or terrible idea?
 

I would do a leak down test to see how much blow by you are getting. What was your compression test method and brand of gauge? Also did you check all the machined surfaces on the block to make sure they are flat, with a straight edge and feeler gauge? If the block is warped it will leak oil like crazy. Also where is the oil coming from? and do not say "from everywhere" it has to be coming from seals, gaskets, cracks, etc. The idea of venting more crank case pressure is good, but I do not see it as needed in this case, the valve cover is a little easy to drill into. Who did the machine work and assemble on the motor again?

John Gosh is a well rounded machinist, not some legend of 4g63 building, thats Rick Shindly.

ROFL... Quote of the year!

And I agree with terrible idea, but its your motor, you do what you like.

Re: bad idea or terrible idea?
 

are you calling him fat? UR MEAN

Re: bad idea or terrible idea?
 

I'm going with terrible idea...


Nuff said, I think. There's no need to re-invent the wheel when there's easier, proven methods that won't PUT A HOLE IN THE SIDE OF YOUR ENGINE BLOCK

Re: bad idea or terrible idea?
 

Fucking Epic.
:scsa:

Re: bad idea or terrible idea?
 

I agree, this should be done.
Wal-Mart, we bought it to determine if a friends engine had bent valves, all i can trust it to do is tell me if i have ANY psi in a cylinder
John Gosh did this for me, resurfaced the block.
not going to rule this out, its possible
From everywhere. JK the whole engine/transmission was coated with gunk and grime, i just finished cleaning the whole assy up today, see attached pic. it was black when i started this. and I have added a bottle of dye to trace any leaks WHEN they surface
I am in no way suggesting that everyone do this, just i think this is going to be a fun experiment.

True, but i learned everything I know about DSMs through rick, back when he was working on DSMs (is he still doing this?)

therefore, I am as crazy as rick.

Also, if John Gosh looks at a block, feels the metal, and says "there should be no problem with block strength if you drill a hole right....there" I am going to believe him over what anyone else here says. DSM pro or not

Oh, how do you like my factory heatshield over my SBR v1 manifold?

Re: bad idea or terrible idea?
 

Well, at least you're not really advertising for SBR, considering the manifold is covered up...

Re: bad idea or terrible idea?
 

Project update: got motor installed, it was a total bitch with that stock ABS. I had that engine at such a messed up angle to get it in there! I hope i never have to do that swap again!

Pictures are of my intercooler piping and my supra sidemount. I know that it is really old school, but who cares? it was free!

I really want a FMIC, but im saving up for a house and I just cant budged it in right now.

Re: bad idea or terrible idea?
 

I heard the engine blew driving it down the block
