Removal - pressure relief valve
Discussion
I have a slight weep from the circlip on my oil pressure relief valve and need to replace the seal. It's looks like one of those jobs that should be straight forward, but could potentially be a PIA! Has any body done this and can they offer advice? I was also wondering if this is possible on axle stands or whether it needs to be done on a lift? I would imagine that removing the driver's wheel would make life easier, but trying to do it with the car down low down on stands would be difficult.
Finally, what size O ring seal does it take? There has to be one cheaper than this!!!

I want to sort my oil leaks out... Just this and the bloody sump... Should be dry as a bone then!
Cheers

Getting it out is not hard as long as you have decent circlip pliers.
It's not an o-ring more like a square section, I just always give them a good oiling and make sure they are inserted squarely as well as cleaning the bore /circlip area before removal/insertion.
I've only ever worked on them with the timing cover on the bench, that's fiddly enough for me
In dire need I guess it could be done in-situ but not ideal.
Cheers spend. Where do you source your replacements? £20 seems an awful lot of money for a small circlip and rubber washer!It's not an o-ring more like a square section, I just always give them a good oiling and make sure they are inserted squarely as well as cleaning the bore /circlip area before removal/insertion.

Just an update on this, as this thread will appear in the search engines and its a pain following incomplete links!
Anyway, I managed to find the correct seals for the PRV, so if anybody is interested, you need a Viton BS017 O-ring seal for the circlip on the PRV for the Serp. It took me a while to find.
However, I looked at the access to complete this job myself and decided to get Dan Taylor at Taylor TVR to do it, simply because it would be very difficult on axle stands. Dan used the same size O-Ring, but his were green in colour and slightly thicker than the ones pictured. Even on a ramp, it was a pig of a job to compress the spring and replace the circlip due to all the suspension and chassis in the way (front wheel removed). Everything was nice and clean when removed, which is good news. The original O-Ring had completely perished (see pic below).
Bottom line, job done and sump resealed again. Fitted a new pressure sender whilst the car was there.
Top work from Dan as usual!
