3k to put rings in?

if you can pull the engine & pop the heads off it really doesn't take long to do the rings at all. (hence, their bill won't be very high).

i'm just in the process of ripping mine out to get the rings done (thanks to detonation) myself.

For 3k you can almost get a brand new built short block.

Leakdown really needs to be done with the engine warm.

An even 170 compression is great. If it runs good just keep driving it. A leak down test is usually done to pinpoint the cause of a drivability problem. I would not get the motor refreshed just to make a leak down test look pretty.

The 170 across the board doesn't make sense with the 30% leak down test. One of the tests was done wrong. And $3000 for a ring only job ...total rip off. Go some place else.
Are you sure you really have a problem? Why did you take it in for testing.
Your post/writing is not very clear/hard to understand.

Thank you for your responses thus far. The reason I had the test done was about 3 weeks ago on my way to work I punched it pretty good and noticed a CLOUD of grey smoke out the back big enough for me to see in the rear view mirror. I had been told that on occasion but not all the time when I take off from a stop at WOT I get a puff of smoke but I cant ever see it. Im only running a few psi over stock and have forged internals on a new block with only 25-30k miles on it, Also I noticed apon entering boost from vacuum the car would bog a bit which to me I figured some blow by was occuring when the pressure was building up. I dont burn oil that I noticed, but those are the reasons I did the test.. Yeah I agree subaru may have F%^&ed up the test because it didnt make sense to me that cylinders 2 and 4 were great and 1 and 3 were leaking. The guy who did the test said he had a block hed sell me so I am thinking the leak isnt as bad as he made it look like cus they wanted to screw me. I priced out other places and they all want about $3k

i asked for a warm test to be done and the tech said there was no point because by the time he got it setup it would be cold and wouldnt matter. I know that was bull$#!^ but thats a dealership for ya around here.

3k is a lot for new rings. The shop close to me quotes near half that...

Also....if the motor cools down too much during leak down...futzing turn it back on an warm it up...if it were my car I'd go find a proper shop/do the test myself.

$3000 to put new rings in is not ridiclous if they have to pull the engine. 1500-2000 just to pull the engine.

It should not cost anywhere near 1500 to r&r the engine. And 3k can very easily get you a new built shortblock. Andrewtech quoted me $900-1k to R&R the engine. $3k is way high IMO.

One of the main reasons for a leak down test is to determine WHERE the leak is ... rings , intake or exhaust valves. Did the mechanic tell you where the leak was? Rings bad enough to smoke, typically cause smoking at all times. Valve guide seals that are bad, typically cause smoking at start up and deceleration. Bad turbo can cause smoking.

What is their indication that it is definitely ring issue? If the rings were at fault I can guarantee you would not be making 170psig compression especially on a cold motor.. Either their gauge is busted, they muffed the leakdown, or both (this is my vote).

The bigger issue here, is that you can't just re-ring the motor and throw it back together without at the very least a light hone. If you don't, the rings won't seat very well and you will likely have a worse leakdown, and more blow-by/oil consumption than you currently have.

A few posts down you say cloud of grey smoke, which tells me it is not oil blowby because it would be blue smoke not white/grey, and its not rings, or it would blow smoke more than just occasionally.

Your best bet is to have Andrewtech yank the motor out, and either let them take care of you, or have them ship it to Justice Racing Engines, and let Jim take care of you. You can get new pistons, rings, have the block torque plate bore/honed, New bearings installed, heads/block decked to be sure of it being flat and true & and have everything in like New condition for $3k or a little more.

The shop told me after I asked three times that " it is definately the rings that are leaking, your valves are fine your heads and gaskets are fine and your compression is good. but the rear two cylinders rings are worn. you can drive the car for a while if your easy on it but id recomend a ring job."
That is what I was told. but it only puffed blue smoke ONE TIME on cold start up but not since. and that was the day after I saw the huge cloud of smoke. I have people fallow me and from light to light I go a little hard on it. One light no smoke, next a small amount of greyish smoke. So I dont know wtf is going on but Andertech quoted me 2 times this week that it would be 3k to re ring it IF they didnt find that the walls were bad, so whoever said Andrewtech would do it for 900 is a lucky SOB. So perhaps the turbo is going bad and thats why it only smokes on hard pulls? Its a FP VF39 running around 16-22 psi in its lifespan of 50k miles on it so far. Thank you all again!!!!

I didn't say a re-ring would be 900. They are going to swap the built longblock in for me with all accessories and manifolds so its a pull and drop in operation. I was quoted 1k to do so.

Id get a second opinion on the engine leak down and compression
