Adrian, if you have retained std ps lines, observe the securing bolt and brackets halfway from front to back of head just in from RCG, undo it and one at front near oil fill tube gives some more room to put yer big mitts in. A variety of 10mm spanners and 1/4" drive sockets are bleedin' helpful in this job, so too a few swear words, handcleaner , rags, head torch .....

see if you can dredge up some gun wash - recycled thinners from a sneaky panel shop that distills it - used to get it for a coupla bucks a litre from a sneaky old panel shop owner

I just need it in a low pressure bottle to feed it in . I'm not sure if it can be bought in pressure pack cans with a nozzle tube .

Actually the Nulon Throttlebody and Carby cleaner one does . They say it can be put through an engine SUEC style to attack carbon/varnish/crud etc in the inlet system .

What have I got to lose ?

Buys new BCPR6ES plugs and they go in 50% easier than 13/16 hex ones , thanks Steptoe . Now I need a 5/8 scale hand to get the plug leads on ...
I cranked through about 1 1/2 PP cans of TB&Carby cleaner and it sounds at times like compression may be coming up on a couple of cylinders . It AAAALLLLLLLMMMMMOSSST tried to cough a few times so theres still a little hope - I hope .
Fingers crossed this TB&C attacks any carbon or petrolium products because it probably takes something powerful to combat Subaru Upper Ebola Carkit spray .

Starter motor and solenoid got a bit warm and the battery current is dropping so back on the trusty CTEK charger and will have another go later on .

I saw your thread on USMB too. Seems they're just as stumped as we are. I'm surprised MileFox and General Disorder haven't said anything yet - I only say this as they've both got loads of grey matter stored info to fix just about anything on a subaru...

Best of luck with it Disco, I hope she comes good for you tomorrow when you try again.

If she does, DRIVE HER LIKE YOU STOLE HER for a bit

Cheers

Bennie

Isn't that the only way to drive Bennie?

Im still surprised there was much crud in this motor. How long since it was rebuilt?

discopotato03 · Post by **discopotato03** » Thu May 31, 2012 11:04 pm

It was rebuilt and went in at around 314K I believe .
Yes it'll get another bash in the morning if I can spare a bit of time .
Ran it all past Coxy and he thinks it may need the power of more than one battery to get a bit higher cranking speed . Also said that starters tend to hog most of the battery supply partly starving the coils supply . Not usually an issue unless the spark is a little weak and the engines struggling to fire for some reason .

Gannon its possibly something to do with a flat engines tendency to gather oil in the bottoms (lower sides) of the cylinders when shut down .
I think these engines should do better than 10/100 and mine tends to run a tad rich because of its slightly non std cams CR and manifolds . I've no idea what its PCV valve is like and must check it out .

Need more cranking amps , cheers A .

Surely your guys that built it cleaned out all the PCV tubes and valve, EGR etc ? I have found some EGRs to be caked in carbon, others RC outlet caked one side, free flowing the other, have spent hours scrubbing these things out with a good degreaser neat, pipe brushes, pull throughs etc. The PCV valve is a service replace item - maybe the 500,000km service interval. Pretty easy to clean them out and give 'em a lick of CRC 556 , though the spider is not the easiest to access from memory.
The load on the starter and battery I suppose was some of the reasoning behind my suggestion of roll starting down a hill - sometimes just what it takes and not the rough old drop the clutch jump start- timing belts can skip on these.

Right now, a cylinder leakage test would help indicate whether it is inlet or exhaust of each cylinder has the bypass - getting test air down exhaust or through TB

I don't own a leakage tester or have a compressor at home .
Latest update is I sprayed a substantial amount of Aero Start in the plenum and started cranking with a fully charged battery . It sounded like it ALLLLMMMOST wanted to catch a couple of times but I think it needs more cranking amps . I had to leave it but not without another big squirt of TB&C cleaner and a bit more of a crank to throw it around a bit .

Anyway can't get back to it until Sunday and will probably try jumping it off another car to get those cranking amps up . Faster cranking speed may increase its cranking compression enough to get it to fire and then I don't aim to let it stall . If I can get it to keep running hopefully it will spit any crud out and possibly even rejig its lifters if they've partially pumped up .

Just for the hill starters , we don't have any substantial hills near here and if it didn't start how to get it back up again . Also the whallopers woldn't take too kindly to us flat towing this thing around a reasonably busy Sydney suburb .

Recall the test method for shagged rings on comp test ? Squirt of engine oil in through spark plug hole for better momentary sealing of piston to bore , not the easiset on flat engines I suppose but may just get a bit around valves too!

I had visions of Coxy and leakge tester, and you two at midnight out on a slight incline - using the Skyline or EVO for a tow back for another go vehicle.

Good luck next go

XX - fingers crossed, not kisses !!

discopotato03 · Post by **discopotato03** » Sat Jun 02, 2012 11:07 am

Well unless SUIC , Subaru Ultimate Ebola Concentrate - IMO , eats piston rings they should be fine .
No don't like the flat tow idea , no vacuum for brakes and issues with the law . Not going there .
I think I'll get there , fingers crossed anyway , just have to beat a car that thinks its a cat in hybernation winter mode . Its spent more time in the garrage than ever and I'm sure it knows where it's going if it cooperates .
I should call it Justy , like someone else I know who won't get up in the morning without a side dump bed .

Well , being jumpered off another car didn't get us running but it did crank a bit faster .
If I have time I'll compression test it again tomorrow and have a look at its PCV valve .

Side dump bed ??? Where do i get one ??

discopotato03 · Post by **discopotato03** » Mon Jun 04, 2012 3:42 am

At the gotta be cruel to be kind mysteriously upending matress factory .
The idea came to me from the missus , reckons she didn't want to know about rising in the mornings as a kid so her old girl regularly tipped her out .

My missus , along with some'ne else , regretted telling me than one ...

discopotato03 · Post by **discopotato03** » Tue Jun 05, 2012 6:45 pm

I removed the PCV valve from my last spare Spider manifold and gave it a cleanout this afternoon .
I also got keen and pulled Ellies out to see if it was clogged/stuffed .
Surprisingly a whole lot of I think used TB & Carb cleaner dripped out and had a go at the paint on the floor . Hard to guess but the pool would have been a bit over a foot in diameter so plenty sitting in the foot of the plenum .
All the plenum hoses are off ATM so hopefully all this will get the chance to dry out .

Will show both PCV valves to Coxy and I have a feeling he'll say they're servicable . If they are cheap I may replace if he thinks it'll help .
I also cranked her over to try and get it to spit any residue out which it did a bit .

Care factor is falling , she is starting to look more and more like salable parts .

Going to have a go with some compressed air and a leak down tester today , don't know what it'll prove but worth a go .

A .

And yes a long suitable hill in a quiet cop free area would be good but don't have that here .

steptoe · Post by **steptoe** » Mon Jun 11, 2012 11:27 am

Might just dislodge crap between valve and seat if you give the engine a chance to kick around on the compressed air.

Listen for where the compressed air supply leaks to, some will be past cold rings into crankcase and you'll hear it in PCV hoses and oil filler tube. If it is inlet valves being held open a tad by gunk - hear noise escape through TB region, if it is exhaust - through tailpipe listening.
I can only think you are sick to the back teeth of this right now. I imagined I would try almost flooding a pot at a time with solvent through spark hole, keeping in mind fluid does not compress, and solvent is flammable . You have been spraying the stuff down its throat only ? Pooling in the spiders belly ??

Once again, good luck !!

discopotato03 · Post by **discopotato03** » Mon Jun 11, 2012 5:46 pm

Yes pretty sick of this saga . Coxys point of the air and leak down was to see if rocking the crank back and forth either side of TDC each pot was to try and see if the air wouod dislodge anything between the valves and seats .
What we learnt was that the cylinders in the RH bank weren't as bad as the turbo side ones . It still almost tries to fire but just never seems enough to actually try to run . We think it just can't get enough innitial crank speed to drive the compression pressure up enough to start .
Coxy thinks if we could get it to somewhere with a long enough hill that wasn't too steep it may turn fast enough to start and run . Nothing like that here and the cheapest way is probably to hire a car float and transport the thing with a friends 4WD .
You have to remember that flying a power steered L "deadstick" means heavy steering and theoretical brakes unless it starts . If it doesn't need a safe traffic free area to pull up in .
