Yes I agree. Will get measurements after tear down and then order pistons. Would be nice if 0.050" overbite was all that I need but I'm not optimistic. What happens after 0.100" pistons are too small? New block, sleeves, custom piston and rod matching?

I used seafoam and it makes a ton of smoke. No idea if it cleans anything. When I took the intake and head off they were still completely covered in soot. I used a wire brush on a power drill to remove it.
What I noticed when I took everything apart is the cylinders are oval, taper, and are...
If you read the manual it says those pressure specs are for a warm engine. The piston thermally expands and closes the gap to the cylinder. Makes a difference but the test is still worth doing cold.
I just replaced mine. Corroded through and wouldn't clamp.
Did the cable burn or the clamp? Excessive current and long starting can melt the lead in the battery (ask me how I know).

I have some thru rust in that exact same area. Was thinking of welding a brace on it. Probably won't last long enough to worry about it though.

I've done the rebuild 3 times including a seized crank. Machinist swapped the rod caps and I didn't check when I reassembled. Was breaking it in and pushed clutch to turn around and it locked up.
Machine shop did an offset grind on the rod journals and I installed oversized bearings. Then I...
I disagree. You only need the starter and head installed to check this. Timing system is required but the Ecu and sensors are not. That said, a leak down test is more comprehensive. THAT said, both are supposed to be done with a warm engine so the Pistons have expanded.

I had some similar issue when revving past 5k. I go the check engine light do cam sensor. Did some reading and wondered if the timing belt was a cause. The belt is around 30k miles and 3-4 years old so I just ordered a kit.
If the cam sensor picks up the cam a certain amount late or early it...
Can we search for members based on location? I'm wondering if there are any ms3 owners in Charlotte that would go with me to check it out.
Just checked the car fax and it was a repo from 2013 and hasn't been driven much. The dealer told me it felt a little underpowered eye he got it so took...
Agreed. Clean the battery terminals and connectors. That's free. Charge the battery and see if it takes a full charge. Then take that to an auto parts store like autozone. They will check the battery and alternator. Might have to remove them first but they do it for free.

It has throttle by wire? Ugh, I like a cable so I always have control.
Thanks for the feedback. I'm sure going from 130 hp peak to 250ish I won't give a crap what rpm the torque is.
That was at 114k miles. I just turned I've 118k and its burning oil again.
I'm pretty sure the source of all these problems is the cylinder to piston gap. I had perfectly gapped rings from the last rebuild. However I did notice some cylinder taper and ovality that was within the factory spec...
Stroking the 1.8 to 2.0 reduces the rod length and increases the force on the cylinder side walls. Stroking up to 2.3 is probably even worse.
Point of this is just that I think people spend way too much time blaming the turbo seals or the pcv when the engine needs to be rebuilt.
A simple...
