Kinja'd!!!

After my little overheating episode, followed by a P0734 code (unrelated) I was finally inspired to get under the Disco and figure out whats what. I don’t have a lift, but “luckily” the Disco is tall enough I can scooch under it with minimal swearing.

The P0734 code has cropped up before and I knew what it was: low transmission fluid. I could only guess, as the Disco doesn’t have a transmission oil dipstick, but sure enough when I popped off the fill screw nothing came out. Unfortunately filling it is pretty awful. Basically you have to run the engine until the transmission is at 104F, put the car in neutral, and then fill it until a 2mm bead of fluid comes out the fill. Then try and jam the bolt back in while fluid drips down your arm and in your hair, trying not to burn yourself on the hot cats that flank the transmission. This time around it was even more fun because, as I said, I found my coolant leak...

The coolant is leaking from the back of the engine. I didn’t even know what was possible. A quick google search says that this is a common problem caused by a failed intake manifold gasket. It only leaks when the car is running, which explains why I never see coolant on the pavement at home...

Problem with that is (A) that meant I had Dexcool dripping in my eyes as I filled the transmission and (B) when you take the intake off a Disco, there are a lot of other little jobs that should be done at the same time. Valve cover gaskets, plug wires, coils, coolant temp sensor and probably a lot of other things I don’t know about. That said: I DON’T WANT TO.

So yeah, I am going to be lame and ask a local shop how much to have all that stuff done. I assume it’ll be $500 to a grand.

Furthermore I also figured out what my belt grumble is! Bad alternator. Spiffy...

That tranny job sounds like most European cars. I’m convinced it’s a racket to keep their mechanics in business.

It’s easier to change the tranny fluid on my wife’s Odyssey than to change the oil. (Insert joke about Honda knowing their trannies are crap). But when something is easy to do, I’m far more likely to do it.

Man, why can’t things be easy?

Dexcool

Oh c’mon, that’s just adding insult to injury!

I would say the quickest way to get an engineer to change his mind about a design like that is to make him do the job himself, but knowing the engineers that I do, I’m not sure that’d work either.

Some designers and engineers need to be beat with a clue-by-four.

i see a parts catalogue pic like this and it makes me upset, upset coz GM can’t make a picture this fucking logical!

fancy that, having all water hoses in ONE pic.

GM can fuck themselves

I recall my dad telling me back in the day, Joseph Stalin used to make car engineers repair cars in -40c. If they can do it, anyone can. If they can’t do it, they go to prison or die. Makes them think twice about their engineering ideas

Perhaps a bit extreme, but it does get the point across!

Coming from Joseph Stalin.... pretty much on par for him.

Hate to be that guy, but head gaskets leak in much the same way very often. In fact, I’ve only ever seen one intake gasket leak like this on one of these engines. If you’re taking the intake off, you might as well just do head gaskets honestly, it’s only another hour or two to get them off.

They also leak coolant down the back of the engine for leaking head gaskets.
