Rocker Shocker.....

[Mr_S]

Heads have been stripped, de-coked, new valve guides fitted, new valve seats cut, steam cleaned all ready for the new cams, Vernier pulleys ready to go on after, looks like new, but....

The big question is, how many rockers am I replacing?????


As a guide to the answer, it's a '97 bip with 15,500m on the clock, and I'm really glad I have a complete set of spare heads with under 1.5K on them......

6

[Mr_S]

higher....

[madmav]

all of them !:burn:

[NBs996]

Well for your sake Mr S, I hope you don't beat my record!

:sniff:

I'll guess Four.

[NBs996]

Hmmm... higher than 6 eh?
Bad luck chappie, glad you've got some more heads!

[Mr_S]

Mav's got it on his second shot.

All of them are being replaced.....:(

[madmav]

mr s what were the cams like?

[Mr_S]

The cams were OK, which was surprising, though most of the rockers are only starting to go, but there were a couple that were really bad.

There were about 3 that would have been OK, but I opted to have them all swapped with the rockers from the newer heads so that they were all of the same age / condition instead of risking the others going in a few months time.

So I now have 2 sets of standard cams (or will have when I fetch the bits after it's all done) along with a pair of late model head cstings, valves etc (but no rockers :) )

How glad am I about buying those heads when I did.

[TP]

Wow - I had 8 replaced and one cam lobe polished!

I am humbled!

[marksduc748]

I have a spare set of barrels and heads complete for my 749s but nothing for the 748.
are they the same?
I am holding on to them for that reason.

[Mr_S]

dunno about 749 being the same as 748, doubt it though..

I've a spare set of barrels and pistons for a 748E that I don't need now though.

[sharpo]

Mine's a 98 bip with 14,000 on it, the service book has two services in it the first on 28/2/03 at 7729 the last on15/6/04 at 13235 so it didn't have a service for the first four years but it's done 50% of it's mileage in the last two years.
What are the chances of it needing new rockers.

[Mr_S]

Mine was a 97 748 with 16K on the clock. So you may need replacements, although the 916 is less "revvy" than a 748 so less of an issue.

[sharpo]

I bloody hope so.

The wifes unimpressed with the rocker story.
Especially with a little sharpo on the way.
