Swampy442 Posted July 4, 2012 Share Posted July 4, 2012 Is it worth it? Is there a procedure? Or would you just change it? My engine is out, and I need to change the front crank seal. The pump was providing good pressure and looks fairly new. What would you do? Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 4, 2012 Share Posted July 4, 2012 Do you know how old it is or what mileage its done ? If you don't i'd probably change it. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 4, 2012 Author Share Posted July 4, 2012 No idea, the engine has clearly been apart in the past and the pump looks quite new. But as you said, if you dont you how old it was, you would probably change it. Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 4, 2012 Share Posted July 4, 2012 (edited) Is there no receipt in the history showing if and when it was replaced ? is there a British previous owner you could contact ? Edited July 4, 2012 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 4, 2012 Share Posted July 4, 2012 Have a look in the repair manuals in the Lubrication section page 12, all the clearances/tolerances etc are there On the homepage top left for repair manuals button Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 4, 2012 Share Posted July 4, 2012 Are you changing the crank seal due to weeping/leak? if so changing the oil pump is a must, as this is the reason for the leak, a slightly worn oil pump will show up via a weeping crank seal, you would never know by the pressure, they will still maintain a very good pressure despite being very worn.

Swampy442 Posted July 4, 2012 Author Share Posted July 4, 2012 The previous owner is on here but the car was modded in Japan, pump wasn't touched in the UK. Ricky it was the wear on the crank nose or seal in that area that caused the leak? Yes it is weeping a bit. Quote Link to comment Share on other sites More sharing options...
listy Posted July 4, 2012 Share Posted July 4, 2012 I just did my crank seal and pump mate. The old pump once cleaned looked brand new. As said, I changed mine just to be safe. With the work required to chi .ge the crank seal, if the old pump stays, then the seal goes again, it's a waste of time. Better to be safe than sorry and just change the pump too. I also took the opportunity to clean the oil pick up, sump, change the timing belt etc as everything was off anyway. Quote Link to comment Share on other sites More sharing options...

Do you know that for sure? is there a grove worn into the crank where the seal runs, does the car have high mileage? My Supra had had work in japan, which i suspect was in an effort to stop a FMS leak, which was successfull, but reared its ugly head again after around 2k after i got it, i fitted a new seal, only to have to do it again along with a new pump after another couple of hundred miles.

Swampy442 Posted July 4, 2012 Author Share Posted July 4, 2012 I won't know that until I get the pump and seal off... I'll just change the pump, save any potential problems further down the line Quote Link to comment Share on other sites More sharing options...
