HG or Newish Motor

My 95 RRC 3.9 is going through coolant quickly and noticed faint white smoke on startup. So here's the dilemma, these symptoms point to HG but also have a ticking only when it's warm and not all the time, usually only after a long drive and a slight loss of power...could be slipped liner?

I'm pretty handy and have restored 2 D90's and a few old bronco's, but was lucky to mostly have strong engines. Should I attempt the HG myself or maybe buy a used 4.2 and try to drop it in, is either of these to difficult for a weekend warrior or do I bite the wallet and pony up at the shop?

Neither job is hard just a bit time consuming.

I'd probably just do the head gaskets, tossing in a used motor is a crap shoot. I got lucky on mine.

I would do the head gasket. Sounds like you are catching it early.
Is not hard and there are great step by step instructions online. If you continue to own rover V8's you will eventually need to do this again anyway.

The best tool I bought for the job was a top side creeper. Worth every penny!

Did it overheat ever? If so it may be a warped head or worse. One of my previous RRCs had a cursed engine. Put several head gaskets on and changed heads but eventually found the problem to be what we will call a slipped liner. It technically wasn't "slipped" but there was a fault in the block allowing gasses to get behind the liner

I think the next five years or so will be interesting as most of the V8s will fail through slipped liners or miles.

Thanks for all the replies, no hasn't overheated only went up very slightly over halfway for maybe 5 min, no coolant in oil, coolant clean but strong fuel smell in overflow tank and loosing fair amount of coolant recently, also noticed a light whiteish smoke on startup in nice warm climate. I watch this thing like a starving hawk and no leaks that can seen and hoses are good and secure.

As far as slipped liner concern, i've got 216k on the clock and gets an ticking once it's warm but not consistent and goes away at higher RPM, noticed a loss of power in top end and halfway traced the sound to what seems like top-middle of engine. I changed the oil to 10-40 and added Lucas additive which helped for about 250 mi and then after long drive in warm weather, came back

Would a compression and HG sniffer test prove anything either way? Waht else should I consider doing while I've got her open, heads, cam, lifters etc?

I'm doing my best to diagnose as much as I can without going to a shop...not so much to save money, but more like a rover survivor man
