Engine failures - Subaru only

[Guest]

Post what shat itself, why - if known, km and spec of the engine. Specify if race car and pics are fun also.

Like so:

Blew a hole in #3 piston due to too much boosty w/no tuney. Stock V5 sti engine running stock J2 ecu but 30psi with a mbc. 210k.

Ran #1 b/e, unsure why just developed a knock. Stock BG5 GTB manual 130k on the engine.

First engine, v2 sti Ra. Ran beb and locked up solid. No idea why with 120000km.

5th engine snapped rod #1 in 2. Due to too much power on h beam rods : D

[funkytown]

ran a beb on #2 from to much powas and beating on an open deck - is track car. had done about 20,000kms

Shredded cam belt when idler bearing seized on V2 wagon @ 230.000 k...Unknown service history and belt looked ok when checked prior to failure..

Replaced with new bits and drove on with no other problems until sold it..

Only time a subaru has left me stranded in 15 years ...

#1 - Oil pick up blocked up due to carbon build up as piston rings were broken, compressed block forced oil out crank seal and lack of oil to bearings seized engine. Engine had done 146,000ks

#2 - Lower coolant hose to the oil cooler sprang a leak, drained whole coolant system, superheated block, warped cylinders, cracked head gaskets and ruined engine. Engine had done around 50,000ks

#3 - thrashed by new owner, killed in less than 10,000ks (exact cause of death unknown)

Ej20g can\'t recall the kms would have to look it up was 2001/2002, Cam belt tensioner bracket broke from block at idle while pulling into a driveway

Put a big hole in the side of the block no 2 cylinder standard engine at that time had a street tune only mod was link g3, downpipe, blamed on the fact it leaned out too much on track was a daily driver then thouh not a race car.

1993 BF5, crank pulley came loose and shagged the keyway, replacing the longblock ended up being cheaper than rebuilding the motor.

BEB, non turbo TS-R at 160kms, probably something to do with 7500rpm sliding around ruapuna

And not doing an oil change before hand?

[F.F.Sltd]

Valve seat fell out of head destroy piston and three other valves 10000kms cause faulty workmanship by supplier

2* blown ring land v4sti running 28psi and antilag 168000

[jost]

RSK B4 with 60,000km, owner in Japan stuck the below cheap nasty oil filter on it and a few days later BEB Failure.

V4 sti coupe

Snapped a conrod heading towards Higgins corner at Mansfield done 126kms standard motor

V8 sti

Afm ran lean and melted piston at 100kms just with daily use nothing to strenuous

Curious as to whether it was lack of servicing or leaking filter.

V5 WRX Engine, melted #2 about 6000KM after rebuild. Person who striped it down and rebuilt blamed "Idiot who rebuilt it previously did a shit job!"

BH5 EJ208 just under 160k\'s blew a conrod through the block.

Unknown; suspicion is overuse of bad fuel; had probably done a bearing beforehand. it wasn\'t my car then lol.

[D-Style]

\'92 RS 140K: Bearing on cam pulley failed(someone didnt change it at 100K) . Threw cam belt. Munch Munch valves for lunch.

\'01 Blitzen 103K: Turbo then BEB. Oil Pick up had crack in a weld, so wasnt sucking up enough oil. No pressure problem, just not enough volume.

[nickmcgill]

2000 BE5 265k suspect BEB still waiting for Richard to pull it apart one day to find out.

Suspect due to changing oil types around 250k to 5w30 fully synth castrol edge.

Was running previously on 10w40 castrol magnatec, genuine filters during the time I owned it.

1998 V4 STI 100k, BEB failure at Manfield. 1st time with semi-slicks on track, BEB appeared after banked corner onto back straight. Oil was 7/8ths full ie a little bit down from the full mark.

2002 BHE GT30 EZ30. Glazed cylinders and worn rings resulting in massive oil usage and low compression on #1, 2 and 3. 200,000kms. Everything inside the motor in pristine condition. Chains looked brand new, bearings were all perfect.

1989 BC2 EJ18. Thrashed the utter piss out of it with noisy lifters due to low oil pressure. After sitting in the driveway idling making a screeching noise from the crankcase, drove it to a mates place. On the way home, #2 piston seized in the cylinder throwing the rod through the top of the block. Carried on driving until the snapped conrod jammed on the liner and locked everything up. About 220,000kms on that one.

Also, someone start the gearbox carnage thread so i can post up a storm.

You know it makes me laugh how many Subaru\'s do the beb and amongst other things.. I think the design of the engine needs to be revisited and sorted if it already hasn\'t been in the newer models! any way #1 bg5a auto twin turbo beb failure #2 bg5a auto twin turbo currently knocking.

People like you are the cause of the ongoing judgement of EJ engine failures from what Ive seen posted on here. The people who fuck with an engine without tuning. V8 sti is where the crossdrilled crank began I believe.

[scoobygt]

You really can\'t say one bad thing on this forum about Subaru\'s with out some one else having a dig..
