the s4 rebuild begins!!!

OKAY here begins my quest... i go to school at edinboro university and im well as you can see preparing to do a rebuild. first was this my garage, it was a mess! but a little work and i got it all cleaned up! i also just got my engine stand, jack and other misc. equipment nessisary for the job.

so i started takin down the block and i noticed oil accumulated in the intake. this is a newer s5 turbo. so i dont know why this is happening to the turbo...but i have been having trouble starting the car and been loosing coolant...i have posted threads all over about it. so this might be a clue as to the problem. i deducted it might be related to the coolant leak due to the coolant in the oil.

i plan on :

-pulling the block
-rebuilding
-stripping the bay
-painting the bay white.
-cleaning pretty much everything and painting or removing any rust or curosion from any part.
-paint the rest of the car after

becuase im kinda short on time there is a chance that i might be sending out the short block to have someone else rebuild it....its not something i want considering i want this experience but, the snow on the hood of the car is evidence enough that working in these conditions is such a bitch. there plent more to come!

so what do you guys think so far

That is quite a project! If you have a factory service manual or even a Haynes manual you should be Ok to rebuild the engine. Do you intend to port it or anything like that while you have it apart?

Working on cars in the winter can be unpleasant, but imagine the frustration of it being sunny and warm outside and you can't drive your car because it isn't finished yet. Winter repairs are worth it. (I certainly hope that your garage is heated.)

As to the oil in the intake, do you know where it can from? It could have come from leaking turbo seals or you may have something wrong with the oil injection system.

Was the coolant in the oil in the intake, or was it in the crankcase oil?

Removing the rust from everything is an excellent idea, you will want to pay special attention to the rocker panels and floorboards, the rear of the front wheel wells and the front of the rear wheel wells.

Good luck and have fun.

no the only heat i have is a karosene heater. its not really doin the job. its ok tho, i want the title of bamf. the coolant i just fround in the pipe, i have taken any manifolds off yet. im tryin to get the radiator off but im having trouble getting the shroud off. any tips?

micah 02-17-07 03:43 PM

I have a similar rebuild project coming up as well. S5 NA. You have any plans to modify your engine stand? I welded up an adapter for the rotary engine. I'll have to take pics as soon as I make it pretty. Still need to drill the holes for the front plate to bolt to.

As for the shroud, don't take it off... just unbolt the radiator and pull it all out in one piece. its MUCH easier that way.

skatingsamurai 02-17-07 04:32 PM

see i tried that but the bottom of the fan hits the bottom of the damn fan! how do you get it out with the shroud on there?

this is the oil i was talking about

micah 02-17-07 06:55 PM

Oh.. you have to take the fan off... its a piece of cake though. Just use a screwdriver to stop the pully.. then take the (4) 10mm nuts off. Pull the fan out carefully (don't drop on radiator) and then the shroud+rad should pull out. Don't forget there are some L shaped metal pieces that hold the rad in as well. you'll have to pull it past those.

Pros rebuild on 5 gal buckets ;)

The bucket is easier to rebuild in IMHO

The oil in the intake is from bad oil seals in the turbo. Sounds like you need to take the turbo to someone to be rebuilt or buy a rebuild kit from a company like mazdatrix.com and do it yourself. That's if you don't want to use this opportunity to upgrade to a larger turbo and get the supporting mods. Search for turbo projects to learn more about running a bigger turbo.

Pros with welders rebuild on a custom engine stand adapter that they made themselves.. :)

Mushy B 02-17-07 07:50 PM

hahaha, i like the 5 gallon bucket idea more

Aw does your back hurt using the bucket? Pros are too busy driving their cars.

micah 02-17-07 09:04 PM

My back hurts LOOKING at the bucket. :) But I'm old....

so does mine...i wish i rebuilt enough motors to justify making a nice adapter :P

micah 02-17-07 10:54 PM

Me too. :)

skatingsamurai 02-20-07 04:03 AM

lol! that is a kick ass idea...its unfortunate i already footed the bill for the stand tho ...::shrugs:: so yeah this upcomming weekend (23-25th) is going to be AWSOME check out the weather for 16412.... 36 degrees!!!!thats so warm! im tottally pullin it is this weekened.

and btw i accually just pulled the shroud off without taking the fan off....::scratches head:: dont know exactly how i did it...but it did it. i made a lil mod for the future too i made a lil 90 degree cut in the shroud under the ingoing hose to make it easier or removal and installing. i hope i dont run in to any pressure problems.

micah 02-20-07 06:24 AM

Well, I took pics of my engine stand adapter I welded up... Took me 45min to cut, prep, and weld the whole thing.... I haven't gotten to the "cleaning up my ugly welds" step... or the "paint it and make it pretty" step.... I accidentally made it about an inch and a half too deep, so the engine is off-center... not a HUGE deal, and definately better than a 5-gal bucket, but... damnit, it must be perfect.. so I'll probably cut it shorter and weld it back together with some gussets or something.

Anyways.. here's the pics:

would you be so kinda as to get me the measurements to that? it looks nice

mort2002 02-20-07 11:50 AM

i think a bird shit on your custom engine stand.. oh wait thats your welds...LOL

micah 02-20-07 03:22 PM

Hehe.. make fun all you want, those welds will hold up to nuclear attack. :) My gas tank started running out, so... I did ALL of that with NO flux core and almost no gas pressure..... You try it! Hehe...

Soon as I'm done cutting and re-welding it so its balanced, I'll take measurements and post them in a new thread. Cool?

"most good...most good" hahaha

Oil in the intake doesn't mean a bad turbo, if it does, i want to know where the turbo is on my 6 port NA, because there's oil in the too.

The oil area(cant really call it a crankcase) vents to the intake, this allows oil to go into the intake at times. If you want to stop it get a catch can.

Unless you have ALOT of oil, then it may be a turbo then.

When oil seal in a turbo goes bad the turbo won't boost as well and when you try to boost the turbo will blow oil into the intake. If your car smokes and oil is dripping from your intake pipes when you take them off (or oil is also blown all over your engine bay from an externally vented BOV) then your turbo is probably bad.

You can tell if its your crank case by running a fuel line (or any hose) from the nipple on the oil fill neck by the block. Put the other end in a bottle, secure the bottle in the engine bay, and go for a drive. Check the bottle like once a day...

Micaheli- the adapter looks like its gets the job done. I think I might have to steal your design ;)

yeah im going to rock the cash box this weeken for sure.. im right near erie its like 15 min south of erie. but i think the turbo is still good because it still boosts like new(knocks on wood) and no oil from the bov. i guess i just wont loose sleep over it.
