Folks,
my engine is on a stand at the moment and I'm doing the usual cam cover seals, cam chain cover seals, plugs, leads, dissi, diss arms etc etc.


Other than being fairly grubby all seems well and she turns over nicely so I'm not going with a full rebuild at this stage (104k).

I have an oil leak from the lower Varioram actuator, I've removed the actuator and the shaft seals are shot (in fact one of them was missing as there is meant to be two) so ordered new seals from OPC.

I'm considering whether to pull the varioram intake off to allow me to test the varioram itself and enable easier cleaning of the surrounding engine parts. Anybody have experience of this?, any tips?, also what have you used to clean the varioram intake itself?, all tips appreciated Smile

I have no experience of doing this, but I have seen it done on Wheeler dealers - the Mike Brewer/Ed China program.

Have you seen the episode where they refurbish a 993 Targa?

I'm sure it's available online somewhere and it was repeated on TV last week. I think.

Anyway, Ed China has to repair the varioram unit as well as seeing him remove and strip it down to an extent he does also provide some good narrative and demonstration about how the thing works.

It didn't look too complicated to remove or work on from what I recall, but worth checking out the program. If you can find it.

The quality of the reproduction was so bad I couldn't watch it and failed to find a better quality version ....... but I am sure I will catch up with some other time when it's a repeated.

Hey,

Which seals is it your replacing on the actuator ? there's the black one that seals the manifold to the unit and there's a shaft seal inside the unit, id change both personally.

If you simply want to remove the manifold its fairly straight forward to remove it few jubilee clips, wiring plug for the evap valve, knock sensor wiring, cylinder head temp sensor and crank sensor wiring, fuel pressure regulator vac line and wiring plugs for the solenoids for the vario ram its self and that's pretty much it i think ...

if you have a vacuum tester check all actuators are working and holding pressure well. there probably wont be much (dirt) as such to clean inside it, just oil tbh. had a few manifolds vapor blasted and must say .... they look good. however did strip them completly to the bare bones. Washing / cleaning them ive found doesnt really do alot. When its off defo give underneath it a good clean, check the trumpet rubbers arent swollen.

Good luck Thumb

P Tek thanks for your response and the results of the vapour blast looks superb. I'll have to look up a local blaster.

Yes the unit is now off as well as the top plastic engine cowling, I had two bolts strip whilst removing but I wanted to give it a good clean underneath to get at the barrels. I've drilled the remaining stud and going to tap some fresh threads. I know they only hold the plastic cowling on the engine but I want it right.

Yes I've bought the large black seal and the two shaft seals, although mine only had one shaft seal which was perishing badly.I'm guessing the reason for the leaky. I'm hoping that will solve my actuator problems.

I'm waiting on a delivery from Rosepassion so I can finish off the valve chain covers, PAS belt and cover, several other bolts that stripped whilst dismantling the engine. I've also bought the N/S engine tin too which was a little messed up on mine.

New dissis and rotors are now on, with new Beru leads and plugs, sump plug, I've cleaned it up pretty well so far with still more to do.

P-Tek, took your advice and got my varioram Unit vapourblasted.

Couple of pics below:







Also had the fan surround done, was tempted to leave it unpainted as the vapourblasting left it looking good but decided to paint it Ocean Blue to match the car body.

Painting the fan housing is one of those totally pointless jobs that REALLY appeals to me! Can't wait to see it all assembled and pristine!

Completely pointless Tobes, but whilst it's out kind of thing...

It was a mess when I took it out, wasn't going to put this back in Hand

Calling P-Tek, I'm struggling to re-install the pipe nozzles as per below, have you re-installed these before?, they need to be squeezed and pushed in at the same time to engage the lip, not at all easy and haven't managed so far.

Any advice gratefully received...

All sorted guys, got them installed tonight Smile

Just takes time with a comfy seat and several different sized screwdrivers to prize the rings into place.

Phew and relax

Folks,
engine is now coming back together, the Varioram is now back on after vapour blasting and various new seals on actuators etc. Just needs final bottom actuator shaft seal, then all vacuum pipes connecting which all seem in great condition and flowing freely.



I seem to have a problem with the alternator belt I have bought which seems way too short, it's a 9.5 x 760, the fan belt in a 9.5 x 776 which seems fine, any ideas??.

Thanks

Trev,

That's odd as the measurements you cite seem to be correct.

I changed my alternator last year and bought two new belts so I just checked the order form for the parts and it was 1 x 760 and 1 x 776, the same as you have bought, and they fitted perfectly as replacements for the originals.

Do you have the ones you removed so you can compare them?

I remember thinking how annoying it was that they had 2 belts doing similar jobs. With almost the same dimensions so why didn't they just make them both the same size.

I think I also remember reading something at the time about some cars having an upgraded pulley in which case a 3rd belt size was required so perhaps you have one of the newer improved pulley's?

Marc, unfortunately no I don't I slung them a week or so ago, school boy stuff I know, I got the new ones from Design 911.

Just been onto OPC and they're saying for my car M64/21 I need 2 of the 9.5 x 776mm vbelts, so I've ordered a new one.

Doh!!
