The alternator isn't outputting anything (I think). The exciter wire, which is more like an input to the alternator that tells it exciting news to motiv...

Round

There is a blue kevlar round tooth belt in the parts locker at the back of the garage

@DecimalDuck happy belated Xmas

I wonder what the oil trap contents look like

I'd be interested in weighing the oil trap alongside a new one to see how full of sludge it may be, something really bad happening causing it to be such an oil burner

Also of note, someone in here previously managed to fuck up what has to be one of the easiest gaskets on the motor. This is par for the course with this car.

This may explain the odd things happening at #4.

Could the head gasket be the original from factory?

It was #1 that was misshapen. I don't think there was any vac leak but it definitely reduced the port cross-section a bit. Given #4 is on the same intake plane it could have had some weird effect, who knows ?‍♀️

I haven't removed the HG from the deck yet, I'll have a look when I do.

Head is torn down ready to go to the machine shop. The flexible claw tool is the perfect tool for pulling the stem seals out.

The stem seals are rock solid. Same for valve hushers. VX3 cam, journals and cam lobes all look nice, no scoring. Valve stems are in-spec. I think even without the head gasket blowing, the head was due for an overhaul. I'm hoping once I get everything rebuilt and dialled in properly we might start seeing something closer to the factory 131hp this motor allegedly makes. I ran the cam on the lathe with some Scotchbrite and WD40 to get rid of the varnish and knock any high spots off the cam seal area.

Any updates on Ron?

DecimalDuck

Brad oh hi, yeah! Ron is going strong, generally speaking. Here's the painted bonnet, now the best looking part of the car haha

I did finish rebuilding the head 👌

Ron has had a few issues since, there was a water ingress problem with the distributor which took a while to get fixed (it was a brand new Bosch dizzy too). The bonnet has also been resprayed to match - @DecimalDuck might have a photo. And we also had to fix the driver's belt receiver. I believe a donor pair of front seats has also been acquired and we will likely mix and match upholstery and foam to produce two good seats.

B6304 swap soon?

Brad

Terrific! Great to see she's still on the road.

I just got my car back from the mechanic who couldn't do anything to fix it. So I'm looking for parts and a better mechanic.

The power steering high pressure hose is leaking and his suppliers don't have replacements.
The water pump is leaking from where it attaches to the cylinder head. Dunno why he didn't want to fix that, I assume parts issue again.
And the rocker cover gasket was leaking at the back again (loose screws so they tightened them again) which is masking the suspected rear main seal leak that I've had for a while. That's the third time this gasket has been leaking.

It's 4 months overdue for engine oil (and filter) change but I feel I need to get these endless and very messy oil leaks under control first.

** Power steering pressure hose:** Get Enzed or Pirtek to make you a new high pressure hose using the old fittings. The OE ones are designed to fail. Also, a Pirtek or Enzed hose will end up being cheaper.
** Water pump & gasket:** Use a genuine Volvo gasket and a Hepu water pump. FCP and the usual suspects can supply them.
** Cam cover gasket:** Avoid using a Pro Parts or Elring replacement gasket, there have been reports of these gaskets splitting and leaking. A Reinz or genuine gasket can be got from the usual suspects. It's also worth making sure the cam cover mating surface is flat and clear of sealant.

If old mate can't even replace a water pump gasket, it's time to find a new spanner person.

I should be able to sort out the water pump seal, pretty sure I have spares. The pressure line will be interesting, I was talking to @DecimalDuck sounds like the failure may actually be in the hardline part rather than the hose. Will have a look. It's one of those awkward problems where to even investigate repairing the hose the car has to be pretty much disabled.

Major Ledfoot

A hard line power steering hose failure would be most unusual, unless there's impact damage or corrosion. Some planned vehicle off-road time to do proper repairs is far better than being stuck roadside 50 kays out of Woop-Woop.

jamesinc

I think the part number for the P/S high pressure hose is # 1330473. It doesn't look like it's available new anywhere though 👎️
