916 Loosing Oil
 

My 916 seems to me buring oil on motorway trips, I'm not sure if I should book it in for a very expensive re-build of look for a replacement lump!
Any suggestions?

How much is it using?

I dont think its a common problem, my 23,000 miles St4 (same engine) doesnt use any so i think i second hand motor might be a better bet.

Or you could get yours bored out, blue printed, cams dialed in etc!!

It using loads!
The strange thing is that I can't smell it burning, I've also checked the plugs and they look perfectly normal. No small spatters of oil either!

My engine burns a bit on 300 etc mile trips where I hold prelonged stints at 120-150 MPH. ( motorway trips)

I guess it would be less than 250 mls. Say from the upper level to nearly the lower level on the sight glass.

I did spain and france on my old 1995 916 back in late may, it covered 2400 miles (before finaly chucking its hand in) and in temps of 34 - 38 degrees and a bit of stopped traffic so got really hot. anyway it used between 1/2 - 3/4 of a litre total in this mileage which i thought was alot as normal uk cold use it just doesnt touch it at all.
perhaps it would have used more if the old dog would have made it back to the UK under its own steam, as i tend to find it uses less when on the back of an AA trailer

On a trip from London the Donnington and back it used from the max level to bellow the min! Now I'm thinking that's not good!!!

Still trying to decide if to go for a re-build or another engine???
Does anybody have any idea how much a re-build wiil cost? With a engine that's buring oil what else is going to happen!!!

If it was me, I would get the original engine looked at. You would then get the worn parts replaced, ( At the most pistons, rings re bore etc) Even get it bored out if that was your thing.

And you would have piece of mind knowing that the engine was reconditioned from the crank cases up. Might even be worth getting the rest checked while it was apart.

OR

You could buy a used lump but no matter what the seller tells you, you would never truly know much about it.

I mean that it might be bolted in, fired up and a month down the line, be burning oil just like yours is now!!

I know what I would do.................;)

Buy a second motor and rebuild it then just swap them over. Rebuild the old motor then sell it on.

Are they plated bores? Dont think you can rebore them as such.

My S4 Monster (same engine) uses oil and apparantly its not uncommon.

How much?
