Yep that was my thought too, but I guess I'd rather err on the cautious side. I lost my first car (a '74 corolla) to an oil problem and keen to not repeat

Draining oil come the morning.

Thanks. It's solid aluminium but I guess that doesn't say anything about the quality. I've seen a range of prices from $100 to $500 for the ProVent, what should I expect to pay?

Incidentally I popped the breather hose off the rocker cover to replace a broken hose clamp and spied this delightful gunk inside. Feel like I should pull a rag on a string through there like my old SLR barrel

I've purchased two Provents for Td5s from Western Filters, Sydney as you can buy each component seperately much cheaper than any kits......

I dropped the oil out of the sump and saw no trace of water. The oil looks freshly changed.

That said, it did have very low coolant on delivery so I'll keep a close eye on that and check the oil for signs of water regularly.

Did the oil smell at all like diesel?

Not at all. It smelled pretty much like the new 5W40 I put in afterwards.

Here's a video of it coming out of the sump, and a photo of it afterward.

If there's no water or fuel in the oil, chances are the head's okay. If the sump plug was overtightened, the last bloke there, may not have used a new copper washer, that's pretty important on these sumps.

If you are not familiar with this engine, it is worth pointing out that they have a very good filter system, so the oil tends to look like new for quite a while - unlike traditional diesels!

Also that other 'plug' which seems confusing if there is a plug there or not, is the wading plug.

You're supposed to plug it with a brass plug that is supplied with the car, when you cross deep water.

Don't leave one in there(if you have yours in the car and decide to use it). rear of engine/flywheel/clutch area can fill with oil/water/stuff and cause problems.

AAAHHHHH thank you. I was worried about that. Guess I should read the owner's manual as well as the workshop manual

When I dropped the fluids in my 'new' Td5 certainly found some interesting things, two washers and thread tape on the sump plug, black brake fluid, and blocked breathers.

Glad there was no sign of water or diesel, injectors washers and seals should be on the list anyway while your doing the injector loom.....

I believe a tuned Td5 is the best Defender engine as long as properly (read meticulously) maintained.
