Sources for a good used or rebuilt 3.8 and 4.2 XK engine
Not sure where the best place to post this is, but like the title says, I'm looking for any firms (or private parties ftm) that can sell me an engine.
3.8 or 4.2, not important, just need a solid, dependable engine. Stock to mildly tuned, just needs to be a no issues sold motor which means it can be a fresh rebuilt unit as well.
Any recommendations for firms that offer this are greatly appreciated...thanks!

Be very careful when thinking of buying a 4.2 litre, because they suffer from cracking between the bores. This then causes constant head-gasket failures. If you want to see how this is fixed, view this video of a US shop doing the block repairs.

I would think there will be few 3.4 or 3.8 engines around now, although you may be lucky. Most "scrapper" engines from Jaguars will be 4.2s from the XJ saloons. After 1982, the blocks were machined differently to cure the block cracking. These are the so-called "slotted blocks", which are very obvious to see if the head is off.

Hey Fraser, thanks for that.
Well aware of this issue, as the engine in my '73 XJ6 ended up getting that very same treatment.
Jim's video was very timely btw...learned all about the procedure as the work was being performed on my engine...after all that, the engine becomes basically bombproof...provided one doesn't over-rev it of course.

Yeah, a decent core is pretty easy to find, I'm looking for something anywhere from "good running used" to "freshly rebuilt"...
...basically, I'm not keen on waiting 4-6+ months to drive the car, and this allows me to get it back on line until the original engine has been done.
Having a spare ain't a bad thing ya know...

Hey Jose, could you possibly link me to this guy in Alabama with the e-type engine?
...I've tried to find the listing on FB, and he doesn't appear to check his personal FB page. I joined the private Jag buy and sell site on FB, but all the offers are located in the UK!
I'm pretty useless when it comes to navigating stuff like FB, and am wondering if it's because I'm physically located in Central America...
Thanks!

No matter who you're dealing with, be it rebuilt or used, an engine with no warrantee is still a risk, sometimes a very costly one.
