Running In

Anonymous · June 28, 2005, 12:21

With any luck my car should be ready tomorrow complete with its new engine - thanks mr warranty man s:)

s:)

The question is though how long should I run it in for or should I run it in at all. I would reckon on approx 500 - 1000 miles but is it needed these days.

Whats the general opinion ?

i was told 500 when i got mine

MrT salesman told me it didn't need running in at all.

Then I got home and read the manual!

500-600 miles, but there's all sorts of theories on the best way. My personal thoughts are: for 1000 miles, don't thrash it (especially not from cold), don't leave it idling for long periods and try not to do lots of short journeys. Of course, they're pretty good rules anyway s:D

Don't let it labour either, that will do more harm than good. s:wink: :wink: s:wink:

Personally, I like what this guy has to say about running in new engines...

You beat me to it! I think the main thing is to work the engine hard through the rev range early on i.e within the first few miles but make sure the engine is up to operating temperature before doing so. The worst thing to do is lots of constant speed driving i.e. motorway work. I think driving like a pansy for the 1st 500 miles is bollox - the engine needs to be worked straightaway in order to get the piston rings to seal properly

Cheers for the info guys

I have read the hard run in info before and it does make perfect sense. Luckily I'll have 6 -7 miles of country lanes to give it some stick and then its motorway time. I'll try to keep loading it up on the motoway so as not to stay at a constant speed (depends on traffic) which should do the trick.

Suppose I had better get those pre cats out as well now or as soon as possible. Another weekend goes out the window s:(

Beleive me, if you're unlucky things can go very wrong. My 2 is only a coupe of years old and the nuts on the 3 studs joining the manifold to the down pipe were bitches. In the end had to book the car into Toyota. Result: 2 studs had to be drilled out and replaced as even they couldn't get them off and the third was so knackered that it wasn't possible to re tap so they had to use a nut and bolt.

Well MR T screwed up yesterday thats for sure !!

I turned up nice and early to collect the car they had assured me would be ready and lo and behold it wasn't. Not only had they not bothered to call me I had also swapped shifts with some else at work to make sure I could get their demo car back for them !!!

Cue a free service thankyou very much

I have now received the car back, this very evening and so far I've had a drive around the block (tipping down) and a quick look in the engine bay. Noticed that there is a new exhaust manifold as well as a new inlet manifold. Now maybe both of these where full of swarf from the wrecked engine but I doubt it. Maybe precats but I know that I am not going to take the chance again. Unfortunately I'm working this weekend or they would be coming out then. A few weeks shouldn't hurt and at least all the nuts etc have been taken off recently so it shouldn't be too hard to get the manifold off.

Just a warning to those who's warranties have expired I had to sign off the warranty sheet for the garage to say the work had been done the total amount for parts and labour was £6580.

Please don't let what happened to me happen to you s:wink: :wink: s:wink:

Six and a half grand? What were they doing? Building the car from scratch?!

Mine were in the same range, don't remember that well anymore. If you take a list price for all parts (and there are quite a few) and add the work, it all adds up. That's why people get used engines, if they have to pay themselves s;)
