new cams.. running in?

[shellz090]

Im picking my gti up tomoz after having new cams fitted along with new head gasket cambelt service etc..

My question is is there any amount of time/ miles that I have to take it easy for?

As I dont want to be doing any damage :)

Cheers

When i got my cam done they ran it in there by keeping the revs at a certain rev level for 20 minutes

Crap.

You will need to go easy for about a week, no hard revving or high revving.

Also don't let it idle for too long.

I thought it might be something along these lines. Id heard someone say taking it easy for a few hundred miles but just wondered what you guys would reccomend really

Run it in, even with just a new H/G I would drive like a old lady for a few hundred miles allowing everything to get seated properly.

Yeh it will take a fair time, When I run an Engine in I always stay below 3k for a day of driving, then start to build up more. And It's always important to make the engine work, stay in high gears. The more the Engine works during a running in posses the more power and longer life it will have.

A head gasket and cam change will not need running in for long at all. only things that really need running in on an engine of any amount of time are the piston rings. race engines that need to be rebuilt every 30 hours are rebuilt from the ground up then run in for about an hour, then ragged to kingdom come

what relevance has that got to the OP in any shape or form?. lol

Yep will get better power but short life... But that how I did mine 200 miles running around then just took it mapping, then just used it

Best way to do it low revs high gear and just full throttle though the rev range so the rings are forcing again the bores.

But only few at a time then allow to cool a bit.

But going on the op question which cams are they?

Newman pre run them in so don't need running in as such... But would be easier for like 25 miles or so then should be fine.

Head gasket on Saxo dont need running it.

ok m8 just what i was told keep you pants on lol

The very first time you start an engine with brand new cams, you do have to maintain high revs for the first 10 or so minutes, can't remember exactly how long or how high. There are different stages to running in an engine depending on the amount of work been done to it, this is one of them. If it is just cams then you can fill your boots after the first start up

Sorrybut this really in not needed.... Head gasket don't need running in. They shoe check for leaks on first start up and bleeding up coolent system. But after bleeded up will be 100% fine if it ok after that.

Run cams into the folders using a bit of cam lube, then roughly 2k-3k for around 20 minutes.

That's what I was told to do, to maximise the lift and minimise the wear on them

[AndySAXO]

Newman say on there cams that only 25 miles low rpm. They pre run them in before selling. But different companies do different things

Yeah definitely, I'd run them in how you're told to do it

[luthor1]

Raunchz is right, 20minutes at 2250rpm solid.

Then after that do what you like with them.

[raunchz]

My logic, which seemed reasonable when i was told it, was that at that sort of rpm, the loads on the cam lobes and follower face are relatively low (when compared to idle), so they can wear in/harden during this 20minutes.

Then after that they have minimum wear and are 'hardened' and ready to drive on.

Seemed reasonable to me and hence i did that.

because that includes cams and the headgasket, and followers, springs and valves, and doesn't take a week.......................lol
