Not unless you want to completely overhaul it. How's your oil consumption? Is it starting well?

Thanks Jack, I kinda thought so. I guess there is a price you pay for 38 mph.

Just curious, is anyone getting +30 mpg with one of these diesels? I read where this is possible so a few years ago and I bought one from a guy in Portland, OR, drove it back to So CA and it got around 20 on the return trip. Later I drove it to Las Vegas and got about the same, but going up hills on I 15 I was repeatedly down to 25-30 mph! I just wondered if someone drove one on flat ground, which is not to be found in CA, would they get good mileage.
I almost got ran over so many time on CA freeways that I did sell the engine and installed a sbc, with aod so I could use the truck. Mine gets over 20 now, and if I can install a FI unit I expect to get close to 30.
There are just too many hills here to drive one safely,
Please courteous responses please, I write this with respect to your opinions and expect the same.
thanks,

I regularly get about 38 mpg in town, driving carefully. If yours was 2wd, manual transmission, you should never get much under 30 mpg. If you do, something is wrong with it.

Now, the rest of my reply is back on-topic, as a courtesy to the original poster (The Dudster)...

There was an improvement added in '84 (too late for the LUVs) that recirculates blowby gases into the intake. The '81-'83 versions have an oil separator, but some oil gets by and comes out the draft tube onto the road. In '84, they added another oil separator on top of the motor. Quite a few owners have made their own systems to capture the oil, and route the gases back to the intake. The key thing is, you MUST not send oil to the intake, or you could cause a runaway engine. 8O And second, you need to do it without causing back pressure, or it will push oil back out the dipstick tube. Here's a good starting place for you. There are other good topics on this subject, too.

Thanks Joe, I appreciate your courteous answer, I was almost afraid to ask the question about mileage. Mine must have been a lemon because I never got over 20 even driving back from OR the first time. I was so diappointed! Anyway that is past history, glad you get this good of a mileage, not many trucks or cars for that matter do nearly as well. I remember back in the 70s when I owned a turbo shop in LV, we would turbo the little VW Rabbit diesels that normally got around 40 MPG and with the addition of a turbo their mileage would increase to an almost unbelieveable 65 MPG! And double the horsepower! Made them almost fun to drive. And turboing a Toyota 20-22R engine brought them from 85 HP to 175 HP with 7 # of boost. Have you ever turbo'd a Luv or Pup diesel, what happened?
Thanks, good to talk to you, and thanks for setting me up on Isuzu Pup.com, am enjoying reading the posts.

A quick fix for blowby, if it is coming from the draft tube, is to remove the cover and place a copper choregirl put scrubber in it. Works for a while.
My Luv averages 38.7 mpg. Daily driver.

not really a far comparison but....

commonly my T\D trop gets 27 to 29 driving from 1,000 to sea level back to 1,000 as a DDer.
26 is the lowest ive gotten as a DDer i tride to run 65\70 mph and got the 26



the max range of mpg is quite large for a trooper.

17\19 mpg pulling a 5,500LB trailer

33+ with modrete hyper mileing on the freeway staying at 55 or less, high tire pressers, mild 10\20mph tale wind.

Oops, didn't look at the post dates. Didn't realize this forum was that low traffic.

It's not that low, but there's not a huge amount of diesel-related chatter here. Most of the users seem to be 1st-gen owners, and the diesel was not offered in the U.S. 1st-gen LUV (unfortunately).

Not picking on y'all, I come from the land of unwanted diesels and have seen slow. I just always thought there were more diesel luvs out there.

I'm currently skimming on jacks site too. We need more guinea pigs it looks like.
