Gary Flinn Posted July 22, 2016 Report Share Posted July 22, 2016 I'm still having problems with leaking seals on the Dizzy to Metering Unit Drive Pedestal of my 5 Can the drive gear wear out and cause new seals to fail? Any advice welcomed Gary Quote Link to post Share on other sites

Guest ntc Posted July 22, 2016 Report Share Posted July 22, 2016 Petrol leak out the hole at the bottom of the casting Be sure? is it a push in return pipe as it should be on a 5 or screw in? Quote Link to post Share on other sites
Gary Flinn Posted July 22, 2016 Author Report Share Posted July 22, 2016 Push on pipe, it's new hose and fitted with Hose clips so no leaking from the pipe? New seals fitted and installed the correct way round and in the correct position. I'm 99% Sure they weren't damaged installing them? It's very annoying, just want to get out and drive the bloody thing! Quote Link to post Share on other sites

Gary Flinn Posted July 22, 2016 Author Report Share Posted July 22, 2016 (edited) I've had a mate blow done the return pipe with the Tank end disconnected and I could feel the Air coming out at the tank end so I'm sure it's not blocked? The return pipe isn't very big diameter though, about 3/16" pipe I reckon, is this big enough? I had a call off my mate who had stripped down the Pedestal, he was concerned that there may be to much play on the drive shaft that runs directly in the pedestal, there was a fair bit of play when he rocked the shaft? So I scrounged another Pedestal off a mate in Derby on my way home, this was stripped down about an hour ago and similar if not worse play was found, is this normal? I would have thought there should be no slop or minimal play or the petrol seal may not be able to do it's job, what do you guys think, could it be I need the pedestal boring out and fitting with a phosphor Bronze sleeve to reduce the play, this is what my Mate thinks may be needed? I've got yet another Pedestal on the way off another mate Dave, if this one checks out the same as the other two then presumably it's normal and this isn't the problem? I suppose i could run a seperate pipe back from the Metering unit return directly into the top of the tank and see if return pipe is actually the problem?

Guest ntc Posted July 22, 2016 Report Share Posted July 22, 2016 Come on then Neil, put me out my misery, what is the problem? Thats better did you do the test? did you shim the pedestal correct? Quote Link to post Share on other sites
Gary Flinn Posted July 22, 2016 Author Report Share Posted July 22, 2016 (edited) I haven't done the test yet because the Pedestal is off the car still with no seals, I'm reluctant to fit the new Seals I bought off Malcolm from Prestige if it's still going to leak? With regards to the shims I haven't touched anything, there is a gasket still where the pedestal bolts down, thats all? I didn't build the Engine so don't know if things are correctly shimmed? I remember doiing this on the Vitesse when I rebuilt he engine on that, must get a workshop manual for the 5! The strange thing is this leak has only started since removing and replacing the Metering unit after having it re-conditioned?

How thick is the casket ( check) you need to do the test as I am sure where the problem is and easy fix. Quote Link to post Share on other sites

BlueTR3A-5EKT Posted July 28, 2016 Report Share Posted July 28, 2016 ...and when it is in bits it is worth checking the state of the two cross pins that hold the gear to the shaft.

Gary Flinn Posted August 14, 2016 Author Report Share Posted August 14, 2016 Update on the Pedestal leak, after having the Pedestal line bored and fitted with a Phosphor Bronze bush were the Metering Unit drive shaft goes through, together with more new seals, everything seems fine now? Went for a 10 Mile run, no leaks Could this be the end of my PI trouble? I hope so!!! Quote Link to post Share on other sites
openroad Posted August 15, 2016 Report Share Posted August 15, 2016 Well done Gary, trial and error ,a good dollop of patience and some good advice eventually cures the problem. Happy Motoring, and keep on top of it all, and the problems get fewer !! Have fun, Conrad. Quote Link to post Share on other sites
