This is '94 3.0 Aero. Oil is mixed with cpplant. I used to remove heads w.o engine pull on my aero. Who did it with '94 aero. Is it possible to remove air intake, manyfold and heads w.o. engine removing from van.
Hey Pablo, I pulled both heads on my '94 3.0 last year. I removed radiator to give me more room. Had a tough time removing the fan clutch, had to pull waterpump and cut it off. Everything else was surprisingly easy for me, a novice mechanic. I soaked the exhaust manifold studs overnight, and they came right out. But it's really an easy job, it just takes some time and a strong back. You should be able to do it with one eye closed and one hand tied behind your back.
Ok, As I've undersood there is no difference with '89 aero. I hope to drop oil pan is easy too....
His engine burns and leaks oil.
I suggest it is time to rebuild his engine (replce rings, gaskets...). I newer saw 3.0 with bad cylinders (sleeves). Bad pistons are rare too, usually after 800K, but oil rings fail in 400K, bearings are "red" when engine is about 400-500 K too. Heads may be damaged with overheating, but he says that his engine was never overheated. I know that sometimes engine soaks oil from liftrs area when intake manyfold gaskets are bad.
pablo,
do you have access to moly coated or chromed 3L rings in Ukraine? these require more refined breakin techniques but last much longer than OEM cast iron rings
also less friction thus better fuel mileage
i've never seen any aftermarket teflon insert skirt pistons for the 3L or 4L OHV Fords, have you? less friction and wear. common now on GM and Ford V8s here
does your '89 3L have the roller lifters or have you changed it over to roller lifters? more HP and less friction.
most OEM blocks here and the better rebuild shops use diamond lap hones and finish the bores to sub 25 RA finishes with 25d angle crosshatching Engine Cylinder Bore Honing

Yeah, available, best are made by Mahle, Schmitz Kolben and other German companies.

3.0 has '89 bore, piston teflon skirt avalable here are 90 ore 91mm. Overboring required. And piston pin is thiker. So some rod jobs required too.

No. And roller lifters are not so reliable, especially if oil was not changed in time

Ones I rebored it to press mercedes sleeves in. Sleeves were ready to use, factory honed.
I have some speleng problems, but 'edit' button desapeared.....
Correct speleng is fogoten art..... Especially in Russian. More then 80% of Russians have serious speleng problems. My GF's mother is Russian Langusge teacher in School. That's why my GF has no speleng problem....
please don't ask me to spell in Russian especially Cyrillic
do you do any porting and polishing work on your 3L Ford OHV engines you are rebuilding? opening up the intake and exhaust ports and runners for better air flow volume since it is a high rpm engine?
i have a good link on porting and polishing. polishing no longer has the negative fuel/air mixing effects that it did with carb'd engines especially with SFI engines. polishing really improves exhaust flow at high rpms.

No. I used to install perfomance exaust and perfomance intake. Polishing works are expensive and... 2-3% HP gaine only.

You are right! At high RPMs only....
Well, it is time to drive to hospital now.... I got cold.... see you later.
i can't help but wonder what it would be like to see/hear an aero drop a gear like honda's and go screaming past some one (in a five speed). it's an awsome sound as it reaches up towards 5k rpms, but then ecu makes it shift... which is lame...
any ways
pablo, don't die! if you do.... can i have your van? lol
ok serious now. so what's the progress on this 3.0 you're working on? full rebuild?

Not sure about full rebuild... I think it is time to replace bearings, chain, rings and seals....
DCRB, I'm not sure I need overbore engine. I have to drive it carefully, becouse my engine kills clutches, trannies, UJs, birns rear tires. Aero is not designed like a fast car and with powerfull engine aero is not so reliable. Ones input tranny shaft spinned and cut teeth of countershaft. I tried to win a drug race with Mazda 6 and won, but drow home with loud grinding sound on all gears exept of 4th. M5ODR1 is not so strong like old GAZ trannies and first of all you'll get with overbore 3.0 (really 3.5) you will get grinding sound on 5th gear.
Guys here recommend Felpro brand gaskets when fixing Ford V6 engine leak problems like you mentioned. I assume the Felpro gaskets stop further problems since I've not seen more posts on needing better sealing, O-ringed head gaskets, or the like.

how about a 3.5l with a 4l auto tranny?
