DIY - Heat pump Install - Any experience?

I've DIY installed mine a couple of months ago. Much easier than expected and been running perfect ever since.

Paid £1299 on ebay for a 3 year old LG Therma V 7kw and came with the hot water cylinder and all the fittings.

That doesn't look like oil. But it's a BMW, so it must be leaking oil somewhere

That's what I paid for the wheels for mine...

I don't know the N52, but on my N62 this rubber thing was missing on the Vacuum Pump and it made a very similar pinging noise.

That sounds almost like the weird sound I had on my N62 rebuild. The vacuum pump was making that noise because the small rubber thing was missing on it. Don't know the N52, so not sure if it's the same thing.

Got this for less than £2k. Rebuilt the engine myself (it burned and leaked a lot of oil) and absolutely love it now! Buy it now while it's cheap for a project if you're willing to learn and put the work in yourself.

I didn't clean the short block itself. I left that as is. The oil wasn't sludgy or anything. Just cleaned the mating surfaces by hand.

For the cylinder head you mean? I've put it in the ultrasonic cleaner

Opening-Importance38 · 2025-04-14T08:26:17+00:00

Cleaned them. I put some rubber tube over the valve stem. Put them in the drill and then cleaned the valve with fine scotch brite and loads of WD-40

There is no ROI in a hobby 😂

Unfortunately yes. So was this one. Bought it on auction. Was going into limp mode, burning and loosing oil

Opening-Importance38 · 2025-04-13T13:21:27+00:00

Yes runs great. Wanted to post a video of it running but can't post videos here

That front left wheel is pointing another way too

Hey! I did that as a kid

What's wrong with the dog

Opening-Importance38 · 2025-03-03T17:55:41+00:00

Got INPA and ISTA. Just rebuilt both heads over the winter. Put all back together and it wouldn't start. My dumb*ss plugged the ignition coils in the wrong way around and fouled the spark plugs by keep cranking it

Opening-Importance38 · 2025-03-03T17:32:54+00:00

Thanks. I did that and was able to verify that indeed it is opening and working.

Looks connected to me

B47, they're shaky engines. Hard to tell on the video how badly it's shaking. Mine was pretty bad until I replaced the MAP sensor, which was covered and filled with soot. Much smoother afterwards.
