You can't do it legally anywhere in the US but there aren't a lot of places they check. They don't check Diesels earlier than the '98 model year in California.

You might want to post a few photos of the engine compartment. You know what they say on Amazon: "People who bought this book also bought..." People who do EGR deletes also delete vacuum amplifiers, aldas and switchover valves. Again, all this may be ok with you, but should have been disclosed. If it's news, then you should at least understand what was deleted and what it was supposed to do.

It beats the alternative.

That's good information. I think I'll need to put in new glow plugs before too long, and I've read about taking off the intake manifold being a good aid for that.

Would be good opportunity for a looksee and a cleanup. I really, really doubt this car's ever been modified for veggie oil. There is no sign of any fuel warmers and the original owner doesn't seem the type from what I know of her. I have friends that have done that, I've always been wary of it. If I was going to get the oil I think I would try the full route and brew biodiesel.

On the other hand, the more I looked at that it would be a lot of messy work for 200 bucks or less a month. And I gather you will have a spot in your shop that will be greasy from now on.

There is an outfit in Berkeley, Biofuels Oasis, that sells biodiesel for about $3.75 a gallon. They claim it's all from waste oil, no palm oil plantations there.

I'll need to look into improving fuel lines however before I do that.

You have a Propel HPR pump at the 76 statation on University. I stop there for fuel every time I go visit family in Marin. Renewable diesel beats the WVO/biodiesel in every way.

I've been out of the loop for a while, first I've heard of it. Found this:

Diesel HPR is a premium fuel engineered to maximize clean diesel engine performance. Diesel HPR meets the ASTM D975 diesel specification (ULSD) for use in all diesel engines. Refined from recycled fats & oils, Diesel HPR outperforms both petroleum diesel and biodiesel in performance, emissions and value. Diesel HPR does not contain biodiesel.

The two bolded parts seem incongruous.

Yup, we had a long discussion going about it here.
Biomass based diesel vs biodiesel
It's manufactured through a different process than biodiesel and the end product closely resembles #2 diesel instead of biodiesel.

I recently learned about there being an alda on the 603. This is good news, I got an amazing power boost on my 300SD from some amateur fiddling with the alda.

Can't tell if this one has been monkied with. Looks pretty normal but it's not out in the open like the SD. I'm going to proceed slowly with it.

By odd coincidence, the long lost Brian Carlton might be visiting my fair city in the next month, he's offered to give it a looksee - the whole thing, I didn't know about the EGR delete when I last wrote him.

My photo hosting thing isn't working right now. I'll post the pics later.

Very clean!! Your mixing pipe has an EGR valve flange which is nicely capped. Are there a couple of vacuum amplifiers between the passenger side headlight and air cleaner? Is there a hose between one of those amplifiers and a protrusion on the front side of the turbo beside the air inlet (ARV)?

Next time you're under the car, check whether the flange between the downpipe and aft section of the exhaust system has 3 bolts or 4 bolts.

It looks pretty complete, other than the EGR delete.

Is there an ARV on an '87? I didn't think they came into play until the 300d 2.5.

Looks like the over-boost switchover valve on the driver's firewall is broken. Just bypass it by connecting the input vac line directly to the intake.

Unless you'll be towing thru mountains with the fuel pedal mashed. Then replace it.

Definitely ARV on a California '87.

The seller steam cleaned the engine bay. Does make for a cleaner operation all right. I've never steam cleaned an engine, I've always worried about high pressure taking water into places I don't want it.

Is the cap you refer to the flat stock here with the two allen head bolts?




I'm wondering if I should check for a gasket there. The fact of the missing gasket at the turbo gives small pause, but I agree, the work does look pretty well done.

The flange you refer to has three bolts. I became intimately familiar with it while doing the recent weld in of the new/used flex joint.

I'll check for the amplifiers later, gotta run.

*ETA*

Doesn't look like there's a gasket in there. Anybody ever modded an exhaust manifold-type gasket? I know you can make them for other engine fittings out of that thin, hard cardboard. But I've not seen a material that is designated for modding hot gaskets. Not to mention most all of them have a thin metal border on all edges and that would be too difficult to pull off on a DIY basis.

OP, I found a real Trap Ox bypass pipe here at the house. Sent you a PM, free if you want it.
