Cerbera with preoiler and new camcover
Discussion
Hi !
After some weeks of waiting for the Raceproved camcover with extra oilfeeds and preoiling it finally arrived last week. I spent almost the whole weekend to fit the kit to my Cerbera but it was worth it as it both made the engine alot more quiet and enhanced the look of the engine. The work was not that difficult to do by yourself if you have a little of mechanical skills.
My car had been standing for one and a half week when i took the old camcover off, by that time the valve train had become completely dry from oil so i think the preoiling system must be a good solution concerning wear on the valve train and other parts of the engine that needs a good lubrication.

I payed £1100+vat for the kit. It was money i had to spend on a upgrade on the car and the things i was choosing between was the camcover kit or new wheels. I know it is a lot of money but i think it can be a good investment for the future since a plan to keep the car as long as possible (forever).
By the way my car had a factory rebuild in august 2005 and has done 6000 miles since then, so the investment is also to try to protect the investment that was done at the rebuild.

It does actually look very nice too 
What does the kit come with?
I notice the connection goes into something in the engine, does this store oil for the initial spray?
Also did u upgrade the oil pump (higher pressure?)
Thanks,
James
The kit comes with a new cam cover that has spraybars inside to feed the valvetrain with more oil, it also has a electric pump that preoil the engine for about ten seconds before the engine starts, it is not the time that is controlled it is the oilpressure which is measured by an extra oil pressure sensor that comes with the kit. The oil is taken from the normal oiltank on the car.What does the kit come with?

It is possible to override the preoiling function if the engine stalls and you need to get it started quick. The pump is controlled by a electronic controlbox. All hoses and wiring is in the kit. The feed to the camcover goes through an extra oilfilter that is included in the kit.

May I ask where you got it from? It looks very nice! Plus should be a big reduction in the number of rebuilds needed.
The kit comes from Raceproved http://www.raceproved.com/ and is sold by Clever Trevor http://www.tvrspareparts.com/Buffoon said:
Good Grief! You seriously need to get out on some wet roads or dirt tracks. Makes my eyes water looking at the sheen on that engine. Beautiful
Thanks !I have been working some with the car since i bought it, this is how the engine looked then:
I think the car has been on both wet and dirty roads before. I just use it when the weather is nice or in the wet if it is a clubmeeting in the Swedish TVRCC or other car meetings.
I like the idea of the pre oiler but I still don't get what it does for the money that a simple ignition cut switch would not do just as well.
Crank the engine with no spark. The ignition cut out switch for pennies would do the job of a pre oiler and add some security to your beloved.
The American Hot Road scene has been using ignition cut out switches as pre oilers for decades.

Errr quite a lot actually. When I ran one of these at Snett last year it took about 8 seconds running the electric pump to generate 10psi pressure on the gauge. I would guess you'd be cranking the engine for a lot longer than that on the starter. The cam cover also has an oil spray bar which puts the oil where it's needed (I believe they made transparent covers durijg development to see where the oil was going) Definitely a well engineered product IMHO. You pays your money and takes your choice. Seem to recall someone saying a couple of months ago you could do the same thing for less than a hundred with an accusump. Having used one of these too, not a chance.

Are you using one this year Ceejay on the Wilder.ceejay
I don't for one minute think they don't work as I am sure they do exactly what they claim, but are we looking for oil pressure or oil coverage. I am not dissing the pre oiler, I just need more convincing I guess as the oil pressure on start up in a normal well built speed six is quick enough and high enough, but for a few pennies you can get a bit of pre start coverage for a bit of peice of mind.
Enjoying the videos by the way you have a good editor.
Hi !
If you turn around a engine that is dry from oil you will have i big wear on the moving parts, so the idea is to put oil in where it is needed before you turn the engine around. With a ignition kill switch you will just turn the ignition of but still turn the egnine around with no oil in it, so I can´t see how that would work as a preoiler.
I have rebuilt my 7.5 litre boat v8 the past winter, before starting it up I was recommended to put a electric drill on the oilpump shaft to get oil in to the whole engine. They gave me this recommendation even though i had used about a litre of oil and special molygrease on the camshaft when putting the engine togehter. What the preoiler for the SP6 does is about the same but it uses an external electric oilpump insead of the internal pump.

While this will obviously help oil supply to the top of the engine, will the cost of the product be recovered in any increase in the life of the engine?
Will we ever find out?
It's great to see products like these coming out for the engine, I guess though a few of us old cynics would need to see some actual proof of a decent benefit before splashing the cash.

I agree with your comments 100%. Will we ever find out?

I have seen one installed, and heard the engine start form cold after running - it's quiet.
While I am in the old cynic camp, products like this make S6 ownership an option for some that would otherwise have run a mile from the idea. A good product that will have a home for many - it appears well engineered.
I said I'd report back:
Like Peppe, my car hadn't been started for a couple of months before I took the camcover off, & just as on his engine my cams & followers were bone dry - not even a thin film of oil when I wiped them with my fingers. I'm glad that I didn't start the engine like this (how many Tivs spend the winter unused.........).
Installation of the camcover & preoiler kit wasn't too difficult, taking a couple of afternoons - mainly as everwhere I looked under the bonnet there were small things that could do with tidying up...
The only problem I did have was the mounting of the electric pump (used to prime the oil sysytem prior to starting).
The raceproved installation has it fitted onto the o/s top chassis rail, behind the front suspension top wishbone forward mount. Unlike the car they used (early? Tuscan), mine has triangulation plates between the wishbone mount & the chassis rail - meaning that the pump would have been 2" aft & too close to the steering gaiter for my liking.
I fitted it onto the chassis cross rail in front of the engine. As this is where the camcover oil filter was to be mounted, I moved that onto the inside of the n/s chassis rail.

Raceproved location for the electric oil pump:
Complete installation showing my alternative locations for the pump & camcover oil filter:
There is also an additional ecu, which connects in line between the original ecu & loom above the fuse box.
In use the enigine is a lot quieter on start up & a bit quieter when running. On start up the add on ecu inhibits engine cranking until oil pressure is registered - this takes approx 10 secs on mine & 6 psi is showing on the display.
I think it's a good bit of kit, which can't do any harm & may well do a lot of good. It certainly elimainates the problem of starting the engine with a dry top end. No more gash silicone sealant on the camcover either (it comes with a gasket).
The only thing I'd change would be for the electric pump to start running when the immobiliser is disarmed (or the drivers door opened?) as well as when the ignition key is turned - so that the time from turning the key to the engine starting might be reduced, at the moment it's a bit of a faff.
