Just had brand new short block fitted to UK MY99 and varying degrees of running in advice came back from the dealer

Chap at service desk says "Just don't red-line it and bring it in in 3 months for an oil change"

Head mechanic says "Just don't go crazy and bring it in after 1,000 miles for an oil change"

Personally I'm siding with the mechanic and trying to vary the revs as much as poss and keeping it under 4k revs (mostly 3k) at all times......

Any input welcome

Cheers

1000 Miles vary revs if pos keep under 4thousand revs, man on desk talking out of his @rse

Enjoy

 

Thought as much Road-Rash

Cheers

 

Sipie,
Got a MY02 WRX in September and was told to run it in for 1000 miles staying off boost (3K and below), worked out at just under 80mph, also told to vary the driving and revs to work the engine through. When the oil had been chnged I was told by mechanic to gradually work it up to 4K to work the turbo a bit for around 500miles and after that gradually build it up over the next 500miles to normal driving (***** out and scared sh1tless )

Now done 6000miles and still seems to be getting faster after a bit of a hammering! Think it takes 8k - 10k to fully run these engines in as thy are so tight!!

Good luck with it and happy hammering

Thanks kin quick

My case should be a wee bit different as turbo, valves and other top bits etc all very well worn in

Cheers

 

Did they identify why the previous one failed?

ie have they checked all the sensors, fuel pressure, oil pressure and injectors for starters?

 

You're going to love the schoolboy error that led to the failure john

PS Kenny... and that 'schoolboy error' was carried out by a mechanic

Do you think I should name & shame

Cheers,

The original prob (ie, flat spot above 4k) turned out to be oil in the boost control valve. I'm maybe not explaining the rest very well due to lack of knowledge but Colin Noble explained it in language I understood and gave me a nice new shiny warranty so I ain't overly worried. Their head mechanic did all the work himself and he's pretty good, so I'm happy (for now )

no problem Si,

it is just that replacing the damaged parts may not get rid of the cause ,it could for example be an injector problem amongst other things,hope you got a knocklink?

 

Sipie

The items in an engine which really require careful running in are the pistons/bores and the crankshaft bearings. These are both new in your case. If you run these in carefully the engine will get better and better.

Kin Quick has given you the ideal running in programme-cant imagine what the bloke on the desk was thinking of!

Thanks Leslie

Actually spoke to IM yesterday (about something else) and when I mentioned this running in lark, he said "first 1,000 miles under 4k, then an oil change and all should be ok"

I will however follow kin quick's advice

Many thanks

 

Sipie,

I would ask for views on why your engine went in drivetrain as to me something does not add up.carbon build up is one thing,but to destroy a piston ,I would have thought that at worse the oil may have been diluted down with petrol.

I also seem to remember you asking for plugs and leads ages ago in one of the forums.it sounds to me that you have had another problem,possibly before the shorting problem nobles claim caused the damage.
