Refurbed engine?

Hiya
Just a quick one.

I've been having trouble with 1800 gti engine losing oil. I could probably have a go myself at sorting it out, but does anyone know anywhere that I could send mine off to and have another refurbed one???

Cheers

I have a reconditioned engine for sale, pm me your tel number and i'll give you all the details.  whereabouts are you based?
