1989 RS Legacy - coolant leak

[wildturkey]

I been tryn to track down a coolant leak and noticed a few leakage marks around the seals of that long rectangular alloy water pipe that sits on top of the

block......and also coolant marks on the block itself.......any1 ever had leakage here before or heard of the seals failing?

I know it will be a manifold off job to fix. Cost of seals and where?...any advice

Here's a few shotz of the seals I talkin bout........not my block

[Guest boostin]

Yeah, just o-rings there, and seen them leak before. Yes the manifold needs to come off.

You'll need to clean up any corrosion on the block and the pipe before fitting new o-rings. Subaru keep them.

yep got it all done thank fark...........took about 4 hrs including cleaning up the corrosion on the bolts and O ring grooves.....damn I scraped out a lot of ***t from those grooves.

Finished it all off with an oil change and MBL8

Now for the test over the next few days to see if it's fixed the problem

Whats the best way to clean up where the orings sit? My CD block has a bit of surface rust and what not in them.

I was thinking that, but does it get right in the recess where the rings actualy sit? did you use a small atatchment?

I used a very small flat head screwdriver to scrape out the corrosion (cause it was quite thick) then a toothbrush to clean it all out. I also smeared the O rings with some red gasket shitttt

[wrx_lou]

Whoa, no wonder they were leaking. Look at the state of them!

[wildturkey]

an a BIG thanks to Jase for helping out ;D

yeah a point tip one, that fitted inside the o-ring holder bit and did a great job, i also finished off the job by using some gasket glue (however a very small amount), just enough to make a nice thin layer around the 2 metal parts

[wrx_lou]

Sweet, thanks. And good job wild turkey

[spark_38]

Yeah that ended up taking a bit longer than the original estimated time of ~1hour ... but we did take it casually, check out a soccer game, had a couple of visitors and went for a wee drive

[wildturkey]

I checked under the car first thing this morning.......no coolant leak so far.....looking promising

[wildturkey]

ok time for a bit of an update.........well after changing my cross pipe seals and changing the

thermostat seal I still had a coolant leak and it was comin from round the water pump so

spent most of today changing the pump and also did the cam seals as well cause last time i

was under the car could see one leaking. Thanks to Stoff for the tools...and Jason once

again who saved me when i was completely stumpd on the water pump (never changed

one b4).....and also to Emery who had quite an innovative way of getting the cambelt

tensioner back in without having to use a vice to recompress it.

here's stoffa magic tool to hold the crank while the nut is cracked.

well got down to bidness and got the pump out

new one in......thanks to Jase :lol: :lol: :lol:

Then we started on cam seals which were pretty flogged

new ones.....

replaced.....

that's about when i forgot to keep taking pics.. :lol: :lol: :lol: :lol:

Emery stopped by to help out with the cambelt especially fitting the tensioner back in cause we didn't have a vice big enuff to compress the tensionor

and the nearest G clamp was a fair way away......

Good news is it's all back together now and no sign of coolant leaks.........fingers crossed

[spark_38]

that seemed a relatively straightforward job, given last weeks mission. at least it's all been done now, and well prepped ready for some track action

[driftrex]

never seen one of those crank tools before, usually the way i do it, and most mechanics lol, is a long power bar resting on the chassis rail behind headlight, with a rag under it, then crank the key for a split second.

but i like your way better ;D good work.

[Guest boostin]

I've got those crank tools too. I got mine from BNT a few years ago.

This is indeed a much easier way,

Otherwise at home i just use the rattle gun and it gets it off in a second

Nice work guys, That is one nice shinny pump, did you brother to clean up the rest of the area? Those seal should last a lot longer now, I found replacing mine made a huge difference and i stopped losing a little bit of oil...

yeah we degreased as much as we could but ran out of degreaser. I cleaned the surface of the block where the pump bolted to and also cleaned up the gasket face of the water pump. Yeah I had oil leak from the bottom cam seals so hopefully the new ones will stop that. The things u learn when u pull ur subie apart!!

So far so good........no oil leaks.........no coolant leaks...........but every time I go for a drive I can't help myself..........I just have to have a look under there ;D ;D
