Cam belt change
 

Hi, done a few cam belts in my time but first attempt at a twin cam....week
99 V70
Engine B5244s
Any special tools or info would be appreciated
Thanks

Did mine recently. You don't need any specialist tools unless you intend to remove the crankshaft harmonic pulley, in which case this is handy:

It is possible to get the new belt on without removing this pulley - just. You might want to check though that the pulley rubber has not perished. In which case it might be worth replacing this pulley.

I'm only removing the timing belt so I can replace the camshaft seals behind one of the pulleys. It's leaking I think due to a blocked pcv system. I'm doing that at the same time as well. And of course
New belt with tensioner . I assume I can just remove the pulleys and change the seals?

If you are removing the vvt pulley (assuming its ME7) you will need the locking pins for the camshafts. If only removing the front pulley you should be fine with marking them, I'm fairly sure the front pulley is keyed, but I will let someone else confirm.

Yes, I believe it is a ME7.
It's a late 99 model with B5244S
Bosh ECU with a lot of Denso stuff fitted.
It has an electronic throttle body which I have cleaned out a couple of times. No throttle cable.
I'm doing the job because it's developed an oil leak on the front of the engine in the inlet camshaft seal. I believe this has happened partly through age but mainly due to the PCV system being blocked.
So I'm planning to do the whole lot at once. New PCV system.
New timing belt and tensioner and of course be camshaft seals.
Car is a 99 on 134000 miles. It's only ever had the CVVT solinoid and radiator changed. Oh, and the usual ABS and alarm faults.
It's never broken down since we've had it(2002)
Main dealer serviced till about 2012.
Now not being driven as my wife has an XC90 to play with but she doesn't want to sell the 70 as she says it her old faithful and never let her down.
Anyway. It looks like I'm going to need a camshaft locking tool so I don't lose the timing?

You will also need a new camshaft end cap seal. It will need prising out to fit the tool and are a single use item. The camshaft sensor is fitted to the other cam hence only one seal.needed.

I'm working off memory but the seal that is leaking is the one to the left with the pulley on nearest the bulkhead and furthest from the front bumper.
My memory muddled me but I believe that one is the CVVT hub as the solinoid is just above it.

Yes, that is correct. The seal I am talking about is at the other end of the cam - a round black cap - that needs to be removed to fit the locking tool. Easy to overlook until you come to re-assemble, then it is b*gger I need a new seal.

Thanks, I know the one you mean. I've read that the exhaust cam on the pulley end needs an O ring replacement. It fits on the back of the CVVT hub. If this correct?

I have never had the need to remove the pulleys from the cams so not familiar with that.
