Leaky rear engine seal

Thanks mate. Will advise mechanic

Yep,
Best advise.
Also check the breather valve on top of the rocker cover to make sure its not putting extra pressure when venting.

Good point GUPatrol.
We have had 2 magnas in 2 weeks with blocked up PCV valves and it is amazing where and how much oil comes out of an engine. One was only partially blocked and it stilled poured out of every orifice.

Thanks Steve

Having not had the mechanical training to know if the mechanic is telling me porkies, I am at a disadvantage. Only two mechanics in town. One is an aggravating bastard and the other the one I use. He works for a business selling tyres and comes in when there is work. So I have to rely on his wisdom when it comes to mechanical things beyond my capability

Yes Wayne :o)))

Hi Dad,
What Greg said above ..... Sounds like it to me mate. I modified the rocker cover breather on mine and found out a few days later the sump was pressurising thus pushing oil out past the seals (front and rear). I put the breather back to its original place and leaks stopped.

Well worth looking at.

Thanks Greg

Hi Son, lol

Cheers

I take it you mean crank wear.

According to the mechanic everything is fine. The truck has 308 on the clock but the engine is still running sweetly, not using oil, and starts first go every morning with no prolonged cranking

I was thinking the same thing Nudie, although apparently the only other one in town "is an aggravating bastard".

Like you Wombat

You bored or on the P*ss again?

Neither, Willem, but like a lot of people who offer good advice to you it so often seems to me that you have difficulty in digesting it.

Now going back to "tors", (I seem to remember shortly after you aquired it)you discovered early on that the flywheel had a 2mm runout. I know nothing whatsoever about the 4.2 Nissan diesel, but I can tell you that the Land Rover flywheel has an allowed limit of 0.05mm (0.002") run out, and the Land Cruiser 0.20mm (0.008") runout.

So here you are seemingly happy with 40 times the L/R and 10 times the L/C limit runouts.

You put it all back together, hell man, what do expect the inertia of that wobble is going to do to the main bearings at 3000rpm? Nothing? Ever picked up the flywheel and noticed its weight?

I could warrant that your crankshaft has been flexing like it was never designed to.

Sorry Willem, its the mechanics chain I should have rattled, not yours, but I hope you get the mains clearances checked and runout brought to specs before the next adventure

kesh

My apologies for being snarky but you do have the ability to wind me up.(refer to this and previous posts)

I am no mechanic but am able to 'fix' things from time to time. I take your point on the flywheel wobble but the vehicle came like that.

Fortunately/unfortunately I live in a small country town with limited facilities and have to rely on advice from qualified trades people who are used to doing things the bush way. I am sceptical of the advice sometimes and try and work around the problem without causing bad feelings likje trying to tell a mechanic how to do his job.

This time round we are going to be more specific in our endeavour to repair the problem.

I will keep you posted

PS My old diesel seldom gets to 3000rpm...lol

The bloody "cabin fever" seems to get to me this time of the year.
Ready enough to go back to work, but still too hot for this ole feller to handle!

My other blight is that some strange gift allows me to do any sort of mechanical work I might need to do. (engines, gearboxes,diffs, steering pumps etc.) A legacy from the old man was a very comprehensive W/shop, lathes, mill, instruments, etc. Allied to the fact that I cut and polish gemstones as part of the income, instead of replacing injectors I make laps and recut nozzles, seats etc. Made up an injector test bench and discovered quite a bit about injector/pump tuning.

I've never known a bad mechanic because I have never taken any of my vehicles to one. But I have seen plenty of results of their incompetant workmanship.

Yeah, I know, 3000rpm was just a figure. My 75 L/C (bought new) has never been over 3000 yet (unless it was in the showroom) I picked it up in the city with 5km. on the clock, and it never went back for any service (including that first 1500 or whatever it was)

Lets know how it goes.
kesh

Thanks Lindsay

Thanks Ray

Will check that too
