Default Hybrid Help

Long story short i bought a bugeye with a fresh rebuild. After 1500 miles i took it to get tuned. It lost oil pressure and started knocking while on the dyno supposedly due to a bearing.

So i took it to the shop that did the rebuild and they at first did not want to warranty anything but finally they agreed if i bought the parts they would do the labor at no cost. So i said **** it and bought a 2.5l block along with all necessary gaskets, parts etc.

Well its been a month and a half and ive had to buy several additional parts here and there. No problem i just want my car done right and running properly.

So they called last week from the shop and said the timing belt was too long and the sti belt was the wrong belt. I assured them that it was indeed the correct belt to use. Then they called back the next day and said i needed a new tensioner. So i bought one and delivered it to them.

Well 4 days go by and no word so i decided to call them and they tell me that on the drivers side its leaking lots of oil from the head gasket and that the head doesnt match the block and the block is too big.
--Any suggestions?

They also say that the passenger side is fine and everything looks correct. There telling me that the STi 2.5l block is not compatible with my 2.0l heads.
How is that so?

Before i have it towed to a subaru specialist and pay out my ass for more work and diagnosis. Does anyone have any suggestions or ideas to how the drivers side head would not match the block but the passenger side would?

Thanks in advance.

was the head checked/decked before sb install? this is a very common motor build that works fine even though the heads and block are different sizes.

sounds like you should bring it to someone that knows how to build a subaru unfortunatly... the 2 liter heads fit on the 2.5 block fine, some people mention the machine work to fix the sizing differece in the heads but something is not right. Brand new block + Heads should not equal any leaks at all. Unless they forgot something when putting the valve covers on... there are those 2 half moons but i highly doubt they would miss something like that.

it could be possible that if they did not torque the heads down in the proper sequence that they have warped and are now leaking.

Well one of the guys at the shop owns a STi and i hope he would know what hes doing especially when coming to proper torque measurements.

What about re-using the head studs?
I wonder if they re-used them.

Reuse is usually ok, torque sequencing is a big issues though

Get it towed to a shop that knows Subarus. Cheap labor is always comes out to be more expensive. I would never take my car to a placed that did a motor build that failed after 1500 miles. You made a deal with the DEVIL!!!!

Find a subaru tuner/builder somewhere and see them. those other kinds of shops always scare me. the boxer motor isn't your grandpa's 350.

I wont be able to have the car towed until saturday but it looks like the head needs to be machined and re-surfaced.
The mechanic said it it had 150 compression across the board except one cylinder had only 20.
