major test run..

[Retro-gone.]

taking the capri for her maiden voyage since the engine swap later today,

gonna clock up 20 miles to start with then come back and check her over, if alls well il go back out and give her a good run for 50+ miles, i guess i should take it easy but for how long?

[OldskoolSue]

I have no idea how long you should take it easy for but good luck and have fun!

If you're running in, you are supposed to rev no higher than 3000 - 35000rpm and exceed no more than 50mph. No labouring in the gears, it's better to change down and be a bit higher than 3000rpm than it is to be labouring the engine.

 

Also, if you're on a motorway, don't sit at the same speed for too long. Vary your speed for a few miles at a time.

 

Do all this for 500 miles then give the engine an oil and filter change. Once you have done this, you can 'drive' it a bit more, but don't rev any more than 5500rpm and no more than 70mph. Do this for another 500 miles.

 

There are alot of variations as to what you're supposed to do, but what I have just written was said to me by an old family friend who's an ex Ford Technition & is how I run an engine in

thanks Jim, im not runnunig in as you would a brand new engine, its just new shells, camshaft and rebuild i have to bed in, i havent had a rebore..

i dont know if i can manage 500 miles without booting it

just boot it, give it a little time to run in but there shouldnt be anything to "really" have any reason to break.

 

especially as you've had it running already on tickover.

ive never ran an engine in (after doing headgaskets and other things) no problems so far

You'll get two answers to this on here Tony

 

1. Thrash it and all will be well

 

2. Break it in gently as Jimbob describes

 

Personally as a time served engineer (of much larger stuff admittedly) I will always go with Jimbobs option 2. Even if you haven't rebored it, a new cam and followers need to bed in together as does a reground crank and shells.

cheers lads, i opted for a steady run..

 

the results are..

1 slight oil leak form camcover gasket.

2 weird squeaking noise from nearside wheel..

3 the paint on the block is bubbling up ..

 

1&2 il sort tonight, 3 il put up with till i take engine out next year..

 

overall the engine is smooth, quiet and pulls well, although i havent had it on 2nd choke yet (i dont think i have anyway, not sure where it comes in)

its hard to resist the urge to plant your right foot when runnin an engine in. I did as jimbob described while running mine in and it seems canny so far

dare i say it

 

sorry haha. 2nd choke on my old one cut in at aroundabout half throttle so you must really be gently running it in if it pulls well already

 

(unless you're running a 38dgas of course, then thats always engaged)

 

oh and dont worry about the cork gasket, just lift up the cam cover wipe it and re-seal it, easy

[X-pack-Glyn]

i doctored the throttle cable to only give half throttle, it helps when running in as theres no way i can stick to 3750 rpm, thats when the fun starts on mine!
