Suspected cracked head? HELP!

[Jakeydee]

Have recently picked up a v2 type ra of what originally thought had a cracked head so plan was to rebuild once the uni semester has finished.

Typical signs are oil in water, water bubbling, white smoke and overheating etc according to previous owner... have driven it for a good half an hour and now confused on whether it actually is a cracked head, the motor didn't overheat, it ran normal temperatures, the smokey exhaust cleared after it warmed up to running temperatures BUT the water DID bubble a little. It also splutters under load and wont boost similar to having a broken afm. Have been suggested it may be an air lock somewhere in the motor and have been suggested to jack the car up onto a 40 degree angle and run it for 5-10 minutes.

Any help on the situation is welcome and past experiences! Cheers in advance.

Good luck jacking up to 40 degrees. Air lock sounds like BS to me. Any oil in the water or water in the oil?

As a side discussion, considering the purpose of the top water tank on a turbocharged Subaru, is there actually any need to raise the front of them?

I've seen mine bled a few times by my mechanic, who is a very experienced Subaru guy, and I've never seen him raise the front to do it.

+1 Just hold the revs up so the water pump/flow can force the air out. Quote from the Fuji Heavy Industries workshop manual:

2. FILLING OF ENGINE COOLANT

1) Fill engine coolant into radiator up to filler neck

position.

Engine coolant amount for refill:

MT model;

Approx. 7.7 2 (8.1 US qt, 6.8 Imp qt)

AT model;

Approx. 7.6 2 (8.0 US qt, 6.7 Imp qt)

CAUTION:

The SUBARU Genuine Coolant containing antifreeze

and anti-rust agents is especially made

for SUBARU engine, which has an aluminum

crankcase. Always use SUBARU Genuine Coolant,

since other coolant may cause corrosion.

2) Fill engine coolant into reservoir tank up to upper

level.

3) Attach radiator cap and reservoir tank cap properly.

4) Warm-up engine completely for more than five

minutes at 2,000 to 3,000 rpm.

5) If engine coolant level drops in radiator, add engine

coolant to filler neck position.

6) If engine coolant level drops from upper level of

reservoir tank, add engine coolant to upper level.

7) Attach radiator cap and reservoir tank cap properly.
