Looking for advice

[Jayz691]

Ok, so I'm collecting parts for a little "refresh" while installing some IE drop-in rods. Be my first teardown of an Audi engine, so some advice be helpful. Not gonna be getting any machine work done, just new bearing, rings, hone cylinders, seals, etc. For bearings, was thinking calico rod bearings, for the IE rods. But for mains, would there be any need for better bearings, or just use replacements? Only k04, possibly hybrid(k04x, etc) down the road, but nothing crazy. Trying ta do this on a decent budget. So don't wanna spend any unnecessary cash where I don't need to. Asking for advice from people who have built/rebuilt these engines, with first hand experience. Appreciate any help, thanx.

i rebuilt mine , but i was merely doing a repair , not for any upgrades down the road, if you are dropping in Forge rods you obviously have something in mind for down the road, so this is more than a refresh. My refresh was just updated pistons and rings, rod bearings, and bolt her back together, i didnt even mess with mains. When " future proofing " a car the sky is the limit and you can get into all kinds of expense quickly.

if you have any questions during your build just post up here. A lot of us have been there and may be able to offer advice.,

[Jayz691]

Don't have much intent down the road. For now, it has 220k miles, so tear down, clean, refresh, and rods. So I can at least take full potential of k04 for now. 99% sure I'll never be interested in doing a BT setup, so don't need anything crazy. The IE rids use tanged bearings, so main reason I'm upgrading those. But I'm thinking replacements for mains/thrust. I don't know the technical side of different bearings and materials, hense why I'm asking. Not sure if getting calico/king mains will be beneficial, or just wasyed money for my power/rpm level.

yeah modded guys will know for sure .. 220K is right up there for sure so good move.

Id just [wrench] any name brand quality rod & main bearings. no need to spend big $$$$$ unless you want to

Thats the only reason really for getting different ones,, figured theres a reason. But for mains I'll prob just go with normal one, from a reputable brand..

never used IE rods. Thought they was the same bearings as stock. my bad then about the IE bearing recommendation. Every motor I installed new bearings I just [wrench] good quality name brand rod & mains bearings. No issues.

Jay,

I've now gone through the rebuild process a number of times with these engines. In addition, I've torn down a dozen or so at junkyards so Ive seen a bunch of them and their innards. I've never built one for power or other than to OEM level, though.

Ironically, you've helped me out a number of times along the way. I'll PM you my contact info, let me know if you ever need my input on anything.

No issues.Yeah, when I'm searching for bearings, theres ones specifically for IE or aftermarket rods. Not sure if theyre "needed", or just a better option able to be used with IE rods. But theyre not too expensive, so I'll go with them. And standard mains/thrust bearing.270227270228

Plasti guage b4 you buy bearings, correct the thrust washer surfaces Audi/vw is known to fuck up.

And pistons if they have no holes in the oil ring land drill 3 on the left and 3 on the right (looking at front of engine block) , clean, check ring gap and install. I lightly hone all cylinders to re fresh the hatch marks. The marks on cylinders walls happens to all of these 2.0 engines. When oil drains correctly it stops the slap stops the markings.

Far as bearings, i know Audi genuine bearings come in color coded sizes, with very slight difference. But the aftermarket ones I'm finding, gor the IE rods are basically all standard, or +.001 . I have zero access or plans to do any machining,, so should I still gauge everything before buying bearings? A big part of this is I can't take weeks ta do it, so really wanna try to avoid having to wait on parts. Wanna have everything ready, take a week off work, and bang out what I can. First time, so I'll be taking my time, but don't wanna waste time waiting days for parts.

I'll be honing the cylinders, new rings, etc. And should the the oil control ringland already have drainage holes??

Based on Fatmongo’s engine rebuilding journey, I would buy new piston oil squirters.

Based on Fatmongo’s engine rebuilding journey, I would buy new piston oil squirters.I already installed 3, gonna grab the other when doing. I'm actually the one who recommended checking the cooling jets. Cuz I went through that last summer.

Ha! True. At the least check the spring tension with a pick!

[Gowking]

Lol, my bad I remember that now.

was that actually your issue ???

there are couple of guys fighting B8s with pressure issues too, i wonder if this issue carried over to the B8 platform ?

[canadianA4B7]

The thrust washers on these vw/Audi have been corrected by few. As I wish I would have. Here’s the link https://www.audizine.com/forum/showthread.php/913645-Main-cap-modification-for-thrust-washer?highlight=Thrust+washer+issue


Its specific amounts of oil to float everything correctly at pressure. That crank has spun a lot in 220,000 miles. The cranks are not true. It has a 30 lbs counterweight below it “balancing” the engine. Ok if it’s your first time, it’s best time to learn engine building correctly. You have no idea how far out each bearing is only 1 way to know so your putting the correct bearings into you rebuild.

Oil rings shud 100% have holes, some engines do some engines don’t I don’t I can’t remember. I don’t have any kicking around to check 4 u.

[Jayz691]

Well, not my first engine rebuild, but first Audi, and been over 20yrs, lol. If I had the money(and downtime) id send the crank out, get it cut and polished, bigger bearings to coinside with whats needed, etc. But unfortunately, I don't. Couldn't even find a machine shop anywhere relatively close, to mill some calipers. I'm just doing this to install the rods, and freshrn up a bit. But I guess a lot will depend on how worn everything is. Itd also be different if the engine was bad in any way, but still runs great. Lots of miles, but everything should be in fairly good shape.. Guess I'll find out, lol.

Yeah, I believe so. I got the engine together and had an issue with the torque converter in the trans, so Im trying to get that sorted currently. However, for the little time Ive been able to run the engine, I havent gotten any low oil pressure lights (knock on wood) and havent been able to hook up a manual guage.
