Hilux '98 ... rear main engine seal repair :( advice please

hi everyone

i unfortunely noticed yesterday that my rear main engine seal is leaking. i have a 98 hilux diesel.

i am looking at starting to do work on my car myself, as i am interested in it. i am no mechanic but im not afraid to look at something new and give it a go. i have a bit of cash saved up and want to buy a few tools (plus grab some of dads).

basically what i am leading too..... is changing this seal a massive job (taking out the transmission, fly wheel etc)? is this task a bit big for a beginner?

at this point in time i am keen to give it a go, but please help me make a decision.

cheers

You never learn anything if you never do it

ive been workin on cars for a while now and everyday i did something new so give it a go u have nothing to lose

but like GOM said do a clutch at the same time and get the flywheel machined aswell

i recommend a excedy clutch a bit more expensive but worth the money and a flywheel machine will eliminate any clutch shudder

but with the gearbox just take ur time and remember what goes where and u should be fine and the rear main is easy to do just dont mark the crank as it will cause the rear main to fail again

but r u sure it rear main and not tappet cover/head/sump or a hose just something to look at

Glenn! Is this the "dodgy mechanic" speaking or the "got a vested interest in selling new(er) 4WDs" magazine chap speaking?

You know that goop is only ever really used when you are going to flog the beast to some unsuspecting purchaser!

well done joe, enough said!

yeh replace the clutch while your at it, always machine the flywheel when you replace a clutch. make sure you use loctite on all the flywheel and clutch bolts, and tailshafts.

replacing a rear main seal is more delicate than hard, best way is to get 2 small self-tappers, drill tiny pilot holes in the seal and screw the self-tappers in, then use them to pull it out. the MAIN thing is to NOT score anything, or you'll have to get a speed-e sleeve to hopefully fix it, which is still never as good. make sure the new seal goes in even.

your clutch pressure plate is probably a diaphragm type - like a big circle with heaps of fingers going from the outside of the circle into the middle of it. make sure you evenly tighten this up right around the circle for a while until it locks up - you'll be pushing those fingers in too.

hope this helps

thanks for your replys.

i have decided that i am going to give it a go and do it myself. and well if i get stuck i guess i can always jump back on here and ask someone who knows.

i will also do the clutch when im at it.

cheers

I own and drive several classic cars (old Holdens and VWs) and am generally wary of 'snake oils'. But, the Wynns stuff has reduced or just about eliminated oil leaks on several occasions. Seriously. It's not an 'instant' fix (give it at least 1000km to work), and won't plug cracks in sumps or other serious problems, but for cars that are old or have been sitting for years, it has worked for me. For about $10, it's worth a shot

Actually - yes.

My 80 has a minor rear main seal leak that has been on the 'watch' list for about 2 years, and still isn't bad enough to warrant any work being done on it.

This is a normal factory fault on TJ Wranglers. I had my rear main seal replaced twice under warranty and once out of warranty when i had the clutch replaced last year. All times the rear main seal has started to get oily again after several months. It doesn't drip any oil onto the concrete below so it's not a landrover.

cheers



Fixed!!!:wink:
