I fired up a motor I've slowly been building tonight for the first time.
Ran it at around 2000-2500 rpm for about 10mins.

Anyone got any specifics they do when running in a Pinto?

I was planning on firing it up again tomorrow night and getting the timing light on it then it should be ready for a drive.

some say treat it like a baby, others say take it up some hills and get it under some load, apparently todays engine components run in from normal driving, no special running in. and to top this off, some also say run it in "how you plan to drive it"

there may be some more knowledged people willing to help, but those are the only tips i ever got [:u]

Hello 2lt_Scort,

Really depends on how tight you have built the engine.

After the warm up that you have already done, check the head gasket manufactures instructions as you may need to retorque the head gasket.

After this has been done just give it a good tune up and drive around as you would in normal day to day traffic without over reving.

Be sure not to keep the engine at the same revs for a long time, vary the revs as you would normally in everyday traffic.

Drive around for 1000km then do an oil change, and another at 2000km
(originally when these cars were new Ford Specified 1500km for the first oil change then 5,000km (I think) then 10,000km etc.

The 1500km to 2000km mark appears to be the time they loosen up properly.

Other people will have their own recommendations, so listen to them also.

Great luck and enjoy!

I have just run mine in and was advised 500ks on running in oil keep it under 4000 rpm, then retourqe the head check rocker clearances and change oil. Will find out tomorrow how it goes with new oil and full rpm

Most run ins are the same principle. Take it for a drive on an open road. Load the engine from low in the revs to mid rev, ie WOT in 3rd or 4th gear. After some time(depens on people oppinion on how long but i would say about 10 min)do the same but take it to 3/4 rev. Once you have done 500km i would drive it fairly normaly and over rev it (red line) untill about 1000km. Like stated above, retention head gasket at about 1000km and change the oil.

is this my old motor Rhys that youve finally got running?

Thanks for the replies. I've got it booked in for an exhaust
Monday so after that I should be able to do the road run in process.

Yep Dave its your old motor....sort of. Cam, rockers and cam wheel are about the only parts from that motor retained.

Had some dramas with it last night and tonight. Dizzy shaft siezed, pulled it apart to find a bur on the shaft, not happy considering it was a recon. Put another dizzy in tonight and skipped a tooth on cam belt so off it all came to reset cam timing and make sure it all spot on again (dont want any bent valves). Will be towing it to get its exhaust done at this rate.

I am pleased to say when I did fire it up it started fire go and sounded quite healthy. Hopefully it turns out to be half decent

The best way guys is to take it straight to a dyno as I normally only fire up the engine long enough to make sure everythings ok and then it goes straight onto the dyno as running under as much load as possible to bed the rings into the bores in most engines it will be done in 5-10mins maximum as I usually do it with the breathers off and you can notice the blow by ceases very quickly with enough load. Once the rings are bedded in we normally take it easy on the camshaft for another 10 mins if it's a new shaft and then into as my own engine will be at full noise within 15 mins.
The trick is to bed the rings in properly with as much load as possible as it literally like driving out your driveway and drive straight up the steepest hill you can think of in the tallest gear you can pull!
On a tour of FPV once through the 5.4lt engine assembly line they were doing just that wheeling hte engine up to the rig plugging in the pre heated fluid lines and pulling the cord and the engines were running alot higher load and rpm than I imagined and thats all the running in they get!

^my engine builder said virtually exact same thign as danny. All we did was bring up the oil pressure before the inital start using a battery drill with an old dizzy shaft then once the oil pressure was up did same thing as danny. My engine builder said just put it under as much load straight away as possible then drain oil, change filter and go.
