P38A Crankcase seal

J L Carr · Sep 12, 2020

Hi Guys how easy or hard is it to change the front crankcase seal as my one is leaking or is there a way too add some sort of sealer to it to stop this,as this was put on my MOT advisories today. Is it worth trying to do it myself or put it in the garage.

Do you mean crankshaft seal? What engine?

Aren't they all pretty much the same? Crankshaft pulley off, hook the oil seal out and tap a new one in?

The diesel needs mega torque on the crank bolt the crank pulley drives the oil pump by friction.stupid idea,why not a key way?

4.0 lt petrol 1998 v8 just wondering if it was possible to change it without taking half the engine out and where to get a seal from.

The front seal is slightly more involved than the rear since the rear can be forced out with a (in my case) gasket scraper...

The front seal, I drilled out using a 1.5mm drill bit, then screwing in a 2mm self tapping screw and pulling the seal out with a vice grip holding the screw and a rubber mallet to shock the seal off it's seat.

The face of the seal has a steel body behind the rubber which needs a drill bit to force a hole through before you can turn a self tapping screw into it.

The rubber somehow "glues" itself into the alloy and will not simply come off without some serious persuasion.

Once it's out and the new seal in, the engine will be happy once again

That'll be why it is usually the rear that fails.

Would it be better to remove the radiator and the viscose fan to get better access to the crankcase seal, I know the crankcase pully has to come off,so just wondering

kermit_rr · Sep 15, 2020

Fan certainly

I would remove rad to give yourself space to work

so which way does the viscous fan nut move and the same for the crankcase pully are they anticlockwise because the engine rotates clockwise.

Right-tighty; lefty-loosey. Diesel has reverse thread.

well new seal fitted, Hooray let's hope this makes the **** at the MOT centre happy as this had been leaking for about 10 years as just a slight weep and if I remember right the last time I topped the oil up was 2 years ago,that was before we went abroad for 2 weeks. But the annoyingly thing is on last years MOT it has an advisory of the oil leak this year it's a total failure even though I only done 1960 miles since the last MOT, I think they wanted money of me to do the job,so going to take it back and then find somewhere else. Thanks Guys for ALL your help.

Looks like it should be further into the timing case ?
