New engine going in

[adf]

Follow up from: http://www.audizine.com/forum/showth...ctured-engines

After gauging oil consumption in my B7 at 1L per 300 miles or so, I had 034 Motorsport do a compression test and borescope. I was particularly concerned about cyl #5 oil fouling spark plugs quickly. Had also pulled a couple of misfire codes on #5 using vag.

Here are the compression results:

4 = 160, 8 = 155
3 = 155, 7 = 150
2 = 170, 6 = 140
1 = 160, 5 = 135

Also found excessive burnt oil build up in all cylinders and oil sitting on top of pistons. Cylinder #5 was particularly bad (no surprises there).

So we are ordering a new engine from Audi. Will report back when it's in but that's probably about a month or so away.

My butt dyno says the car seems to be running great, but with compression numbers like that and so much oil consumption, I'm guessing a new engine with better compression is going to run much better.

Whoa, what's the price tag on a new engine from Audi? Did you get a long block, or just a short block?

[Mr.Wrong]

Last I've seen posted prices on new short block from Audi was somewhere in the neighborhood of $10k, and slightly over $13k for a longblock. I wonder what Audi charges these days, so same question^ hopefully you don't mind disclosing. Have you confirmed is it's going to me remanned one or brand spanking new?

It's a long block, part # 079100031DX for just under $13k. Was told by 034 that Audi had some problems a while back and doesn't do the short block any longer. This one comes with a 1 year, 12k mile warranty.

Have you confirmed is it's going to me remanned one or brand spanking new?

Supposedly the engine is brand spanking new. There is a core to be returned though so I suspect it may not be a newly minted block.

Wow, spending 15k on putting a brand new stock motor in a car that on a good day is only worth 15k has got to be the smartest thing I've heard in a looooong time.. You must be a dealership's wet dream.

To each there own. So get off his balls. No trolling needed here.

[s4ski]

Whoah, that's a chunk of change . That's commitment, I will give you that. Are you going to add some mods before you put it in?

Heh, well if we all optimized for rational, financially responsible decision making when it comes to car ownership, we would all be driving toyota corollas. Not Audis, and surely not S models.

I'd trade up for a new S4 or a Golf R but I don't like either of them anywhere near as much as this car. And if I've learned anything in my history of car ownership, it's better to spend money on a car you love than to rationalize spending it on a "better valued" vehicle you are ambivalent about. Not that any of us need to justify our choices in cars, especially here, but that's mine.

Not much really. I am putting in the 034 control arm kit and motor mounts though while the engine is out.

[WCCoffey]

You're absolutely correct... but spending that kind of money for no gain is kinda like beating your head against the wall. IMO, spending that kind of money on a car and keeping it stock is solely for cars that will appreciate in time or are considered a collectable car that wont continue to depreciate massively like our cars will.

Spending 15k+ could have netted you a JHM built motor with a Supercharger Kit. Then you'd have a reliable motor that doesn't burn oil and makes like 500hp... Seems like a much better investment considering cost vs. reward

[IslandHydro]

I gotta say I don't understand why people are panning him for this, I totally get his point of view. I love this car, and can't really see another that I rather have at this point, so I for one understand this, and I'm glad the option is still available.

[QIKRNU]

Hey, man. It's your car. Do what makes you happy. If, in the future you want to make changes, you can.

A JHM motor is intriguing. Not necessarily for the power gains, but the fact that they sleeve the aluminum block. I wonder what their waiting list looks like. Saw a reference to a total bill of around 30k for a built engine + SC setup from them.

[S4orgy]

Yea i would've atleast put that 13k torwards a built block incase later down the road id want to add a blower especially with all these other new cars jumping up in power.

[hkdolphins]

I saw ebay brand new one for $10K. Should those tensioners been replaced with updated JHM parts before put engine in?

I think I saw the same one and discussed it with the service dept at 034. Looks like an engine built by Overland but I wouldn't get a labor warranty from 034 getting the engine third party from eBay. So I decided to go with a factory motor.

Should those tensioners been replaced with updated JHM parts before put engine in?

That's a great point. Any pointers on the increased durability of the JHM tensioners?

See that X at the end of a part number, iirc it stands for remanufactured. I'd do some digging just to confirm this.

Great minds think alike. Couldn't have said it any better.

$15k would not yield you a built motor with sc. That's quite an optimistic number. Built bottom alone is $10k, add to that their hd heads then add their charger and a must have supporting mods. A bit more than $15k wouldn't you say?

Yea, it would be around $22 grand all told purchase the engine, supercharger kit, and install if you arent doing it yourself. Add in miscellaneous freight fees if you are sending your engine to them

[Mr.Wrong]

^I see a withdrawal kicking in

[Mr. Corey]

OP i couldn't agree more!!! I debated over investing the money to rebuild my heads and timing etc VS. getting into a new ride and after test driving a the new offerings from Audi and VW i wasn't impressed. So I bit the bullet did a rebuild added a few new mods and couldn't be happier!

It would be more than 22k for parts alone not to mention you have to ship your car if your not local so add another 2-4k for that.... then they do the install and break-in at their facility. When i reached out it was roughly 30-35k for a stage 2 hopefully the price comes down eventually!

[LINDW4LL]

OP, do you have a warranty?

No warranty unless a previous owner had one. Can you still buy a warranty?

Pretty steep but still cheaper than trading up to a new S4. Maybe once this new motor goes south in a few years this would be a good path. But hopefully we get a decent new RS model in the states before then :)

Just wondering why someone hasn't found a machine shop to sleeve the block for them and use stock pistons and rods, or get a set of forged internals.

Respect

If nothing else, I would install headers before dropping in the new engine. The S4 will never match the RS5, but nows the perfect chance to transform the sound and add some low end torque.

The JHM longtube headers require cat removal though right? Don't think I could get away with that in California. Was thinking about doing a JHM intake manifold though.

you can order your test pipes with your headers however you like. I would highly recommend them in combination with IM they really transform the car!!! Maybe even show your stablemate whose boss lol

Theres a shop i found that claims they'll sleeve our blocks for 2800

IIRC wasn't there another member claiming he found a shop to sleeve his BHF and going to do it... Will they warranty their work?

[sandspeed]

I'm interested now. This plus a low-pressure blower could be very fun. I've also been told that 2.7t rods are dimensionally identical to 4.2 engines. Someone needs to confirm this though.

I've been chatting with them, and they've done it before. I'm planning on doing this when I get back from a long business trip I have coming up. They also recommend going with Wiseco or Arias pistons and they will bore the sleeves to match.

And IE has some for nearly half the price.

[LINDW4LL]

4.2 and 2.7T rods are exactly the same to the best of my knowledge. I've heard this stated many times in the past, and both are 154x21 and have 100% identical specs on Integrated Engineering's site.

Any thoughts on cracking open the new engine and adding the updated JHM timing guide while the engine is out? How difficult is this piece to swap out on a bare motor in terms of labor? Sounds like the part is only $60 from JHM but worried it may take a lot of labor time to swap the part even with the engine already out.

Most of the labor on a timing service comes from actually pulling and reinstalling the motor. So once it's out it shouldn't take much to install new guides. Definitely a must do once your motor is out for whatever reason.

Now for the catch 22 -- do I swap out the sprockets and updated guide and risk voiding the new engine warranty. Or do I leave this job for later knowing that in 50-100k miles I'll need to pull the engine again.

I am curious if anyone has experienced timing failures on a relatively recent remanufactured Audi engine.

Catch 22 indeed. What does their warranty cover, mileage/timeframe?

1 year / 12k miles
