Hello,
I have a 1995 SPI that was imported from Japan last year. I did an oil change last month to the Motul MA2 that is recommended for the auto boxes, new filter etc. Ever since I've changed it the rubber o-ring keeps blowing and I have to replace it. I'll take it out for a wee drive and it blows again.
Could my oil pressure be too high? I've bought an oil pressure gauge to check which I'll fit at some point this week. I was also looking at it possibly being the pressure regulator valve has gone bad which I am going to replace too (replacing because I'm running out of options as to what is wrong).
Just wondering if anyone else has had this issue?
Cheers!

Here we go again! this a frequent complaint and has been trouble shot in the past, (must be possible to dig out old posts) Are you sure you dug out the old seal it has been known for there two seals in the groove, Are you sure the bolt is tightening down properly and not becoming threadbound. If the bolt is overtightened the end of the bowl begins to collapse. A couple of photos to show what it should look like, Jock Attachments:

I had a good look through the previous posts on the site, think I've read each one twice over the past few weeks. There's definitely not another seal in the groove and the bolt is tightening down nicely. I had the issue of overtightening before and had to buy a new bowl, sadly experienced that with all my new oil shooting up the fence! I'm hoping it's the regulator valve but I'm really not sure. Attached some photos, blown seal and where the leak happens on the bowl.   |

Gee I don't know, The bowl looks to be nicely inserted, do you get two seal rings with the filter I always seem to, I can't remember which one I use, same as the old one I pull out. I find it amazing that there is enough pressure to actually blow the seal. The oil pressure control valve is inside the valve block so its a big job to get to. I believe there is a tapping point on top of the filter head where you could try a pressure gauge,(200 psi min) I just remembered there are two ball relief valves in the bowl head, hard to believe they would both stick, no idea what pressure they are meant to lift at but worth checking.

Tarija and Santa Cruz, Bolivia
I, too, have had many problems with that, but have found (so far) that the solution is enough oil on the new seal, and pressing it gently and completely with a flat screwdriver down into the groove. If it is dry, it does not go in straight or completely.
In Reverse, you have about 175 psi in there. Hard to imagine that the pump would put out much more than that.

The AP2 has 2 pressure points... one on top of the filter housing which can be seen on your photo and the other is on the front edge of the auxiliary pump body, I have a VLC-18G502b pressure kit on my website please see above.. |

Has anyone on here seen the japanese replacement filter bowl, similar design, but better quality, it did work out about 450 quid though!.

Someone put this up on one of the other autogroups on facebook, looks well made, i have to say the mini filter is a nightmare.  |

I was trying to work out, if the bolt head is independant of the canister.
