scaleless Posted April 22, 2021 Share Posted April 22, 2021 Especially after factoring in shipping, reman blocks in general are just not very cost-efficient. Get a local machine shop to clean yours up or if it's for some reason beyond repair, just pull a block out of a scrapyards and bring it to the machine shop. It'll come out to way less.

jdog Posted April 22, 2021 Share Posted April 22, 2021 And should be built correctly if the machine shop is competent. Link to comment Share on other sites More sharing options...

Good points, I can get it shipped for free. I won’t be doing the work myself (I don’t have the tools, skills or a garage to work out of) and have a reputable shop that will stand behind the install. I am looking all in at around $3800 which also includes rebuilding the AW4. Link to comment Share on other sites More sharing options...

With a Haynes manual and no experience at all, I did mine all-in with the cost of tools and everything for just under $700. As for the original question, I don't know much about Dahmer. But I also haven't heard anything negative, for what it's worth. Generally I've found that if you're not getting your engine done by Bubba down the road and you're not trying to squeeze out 300HP over stock, you're probably good to go.

It idles fairly decent but has a miss that we haven’t been able to diagnose. Also I am wanting it to be a true daily driver and occasionally a long hauler. Wanting this one to be around for a long time. I know I’ll have things that need to be worked on hell it’s 34 years old, but I need it reliable. I’ve got all the wiring except the AC sorted and fixed along with the majority of the suspension and brake system. Link to comment Share on other sites More sharing options...

Pete M Posted April 23, 2021 Share Posted April 23, 2021 'tis smart internet research is free what color is the smoke? Link to comment Share on other sites More sharing options...
CGCWO Posted April 23, 2021 Author Share Posted April 23, 2021 White to light grey. Heavy oil smell. Thought it was a open injector at first since I had a open injector #5 code from the REMII. Found the problem there (injector ground was not good) pulled the wiring harness apart (again) and re soldered the connections. Also double checked all the other work I had done to the factory splices. Everthing wiring wise is good now, I do have a small amount of oil in the filter (this isn’t a big deal) as I know. I know all the sensors are good (TPS, MAP, IAC) vacuum lines are all good, new plugs, wires, dizzy, upgraded battery cables, new alternator and radiator/195 degree thermostat. Cooling system has been burped and it’s not running hot. New MTS fuel pump, fuel pressure regulator, Volvo 746 4 hope injectors, new O2 sensor. Symptoms: low idle at start up, then levels off to 700-750, sometimes it dies and have to restart. i get a lean code on REMII then after running it jumps back and forth between lean/rich. First 3-4 miles it runs fair but is under powered. Shifting is jumpy and will barely pull a incline. Then the smoke starts, the longer the drive the worse the smoke gets and the power seems to get weaker. Have a hard time maintaining speed and rpms.

Pete M Posted April 23, 2021 Share Posted April 23, 2021 I don't think this is the main issue, but is there any oil dripping down on your exhaust crossover pipe? mine did a similar thing and it was oil dripping on the hot exhaust. caused a strong oil smell.

ghetdjc320 Posted April 24, 2021 Share Posted April 24, 2021 Smoke color sounds like coolant. I’d guess you have a head problem. But that’s just a guess. A comp test will get you some more info. Link to comment Share on other sites More sharing options...

Yes there is some oil getting on the exhaust, it’s from the rear main seal leak and maybe some from the trans pan gasket. Link to comment Share on other sites More sharing options...

Didn’t get to it today, was a bit under the weather after having my second shot to activate the new government tracking device. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted April 24, 2021 Share Posted April 24, 2021 You won’t see water in the coolant all the time. Depends where the head gasket blew or head cracked. ~75% of the time you won’t see milky oil at all though. Link to comment Share on other sites More sharing options...

Didn’t get to it today, was a bit under the weather after having my second shot to activate the new government tracking device. Okay got the compression test and fuel pressure test done today. Let’s start with the good news, fuel pressure is all good right at 32psi at idle vacuum line connected/just about 40psi v-line disconnected. Now the bad and what was suspected. Highest compression came from #1 cylinder (52psi) yep that’s right 52psi, low was #4 at 31psi. This explains a lot of things (smoking when warmed up, no power under throttle, inability to climb a ant hill, etc....) Had a mechanic buddy watch how I did the test via FaceTime to make sure I was doing it correctly. I am really amazed the thing is running and able to move its own weight.

CGCWO Posted April 25, 2021 Author Share Posted April 25, 2021 Questioned my testing results. Went back and ran test again, similar results with 45psi being the average across all cylinders. High of 58psi and low of 38psi. I miss read the numbering for the previous post. Either way I got a problem and need to address it. Also did a wet test and the numbers didn’t change more than 5-10psi for each cylinder. From what I can find I’ve either/or a combo of all the following: valve problems (but not ticking), head gasket problems, rings and/or possible head crack.

ghetdjc320 Posted April 25, 2021 Share Posted April 25, 2021 Is your battery fully charged Ned did you have all the plugs out? You need a minimum cranking rpm of 400 to get accurate results. Also remember that what your really looking for is significant inconsistencies between cylinders. Significant is normally ~20psi difference Link to comment Share on other sites More sharing options...
