Seals on the timing belt side of the engine - sanity check

Anzezaf · Post by **Anzezaf** » Tue Mar 31, 2020 4:19 pm

Hey guys.

I sprung an oil leak around the crankshaft seal and I decided to just swap out all of the seals on that side of the engine since it's an off-with-the-timing-belt job anyway.
Now, can someone just check if I forgot any seal that needs replacing?

1. 1x Crankshaft seal
2. 2x Camshaft seal
3. 1x Balancer shaft seal

That's it, if im not mistaken?

I believe there is also a seal for the cambelt tensioner? If you still have the original one, its oil pressure fed (ATR84 had a long post about it leaking in his).

I'm not sure if the tensioner has its own seal/oring , in addition to leaking internally from the item itself?

I did my timing belt 10k miles ago, so the tensioner is new. No worries there

Just to clear this thread up, there is no seal for the tensioner and it is not fed with engine oil.

The tensioner does contain a few ml of oil for self lubrication, but tension is provided via an internal spring.

@Anzezaf my cambelt had been changed recently but was still leaking from behind the cambelt cover because the person who did the replacement basically just changed the cambelt and nothing else. They didn't renew any of the seals or the auto tensioner. Performance Autoworks fixed it all for me and converted it to a manual tensioner in the process

Get the balance shaft seal retainer kit - this should prevent the seal popping out in the future.
the kit is only a few quid from Honda-it also includes a new oring for the bottom of the dip stick tube

Ages ago, I did a post listing all the parts needed for this job - with images.
I think it was added to the wiki, but that isn't working atm.
I'll try and add it as a sticky in the engine section when I can, but in the mean-time, I've tracked it down

viewtopic.php?f=5&t=18534
Here ^^^^^^

(I will also need to fix the links to the parts diagram images embedded in that, since it seems they've broken atm)

EDIT: Now made sticky and images fixed
