Unclejake Posted February 6, 2019 Posted February 6, 2019 What if I filled the entire engine with diesel from the oil filler tube, let it sit for a few days and then drained it out. Reckon it'd creep up past the rings? 1 Quote
Yowzer Posted February 6, 2019 Posted February 6, 2019 That's a very unusual story. How would you overheat the oil without over heating the water? If there wasn't enough water in it the temperature gauge wouldn't have changed, I had that happen to an engine once when it blew a hose. If it has been proper hot then things could have warped a bit. Bores may not be round anymore. Might just be worth ditching this one and slapping the turbo gear on that other engine. 3 Quote
Mof Posted February 6, 2019 Posted February 6, 2019 Drop the sump and check the big ends? Probably can't, some crossmember in the way or something murican. I've had the v8 out of a f450, took the cab off to get to it. 1 Quote
Unclejake Posted February 6, 2019 Posted February 6, 2019 Yeah, it's 4x4 so lots of rusty stuff in the way. I think the filling the block up with lubricant idea has some merit (thanks OS). I hadn't thought of that Quote

By running a bearing. that will get the oil hot very fucking quick and zero change to coolant temp. I will say that i work on truck motors and not smaller vehicle so it might be different. But in my experience is if the oil temp raised so quick it didnt get to the cooling system, thats bearings , they aint part of the cooling system and thus the oil will hold ALL of the heat. Yeah there are oil coolers but if you watch coolant vs oil temps while running up you can see how lagging/ disconnected they can be. Not a wail, but my experience. tear me apart if you will. 3 1 Quote
Hemi Posted February 6, 2019 Posted February 6, 2019 Atf is good for freeing up bores too, has the detergents in it for that, wont evaporate etc. As for if its a bottom end issue,try turnign over via crank bolts? if these slack then it might be in the pistong rings. if theres none its in the crank. 1 Quote
Testament Posted February 7, 2019 Posted February 7, 2019 check the negative/earth connections of the batteries to the chassis and engine to chassis if you can, bad connections there could also cause poor cranking while hemis explanation sounds plausible it seems very odd that you would even know the oil got overheated without a temp gauge unless he has some story about the thing seizing up and smoking out of the breather or oil cap with the temp gauge cold or something like that. Which he would have told you? or is he being a bit cagey about exactly what happened to it? Quote
cubastreet Posted February 9, 2019 Posted February 9, 2019 How hard is it to rebuild a diesel injector pump? I can get a good deal on a 93 surf (2LTE?) that has a leaking pump. Quote
Yowzer Posted February 10, 2019 Posted February 10, 2019 Yeah my thoughts exactly (re: Tom's post). I've personally never seen a "small" engine cook the oil from a bearing failure, generally because it either makes so much noise, locks up or spits the rod before it gets a good glow on. If that is what happened though, or any failure that results in overheated oil, I think it's pretty safe to say it's an anchor. Quote
M.H. Posted April 16, 2019 Posted April 16, 2019 What egt gauges are you guys running, dont want max china spec but dont want to spend $500 either Quote
Yowzer Posted April 16, 2019 Posted April 16, 2019 I can't recall the brand of the one I was gonna get, which is annoying me, but it was about $400 and combined EGT, boost and whatever additional temp sensor into one unit. I think the scales could be adjusted too Edit: this might be the one I'm thinking of, if not it's very similar. https://www.redarcelectronics.co.nz/monitoring-gauges-g52-bet Quote
M.H. Posted April 16, 2019 Posted April 16, 2019 That gauge only goes upto 700°c. Would be nice if it went to 900 Quote
UTERUS Posted April 16, 2019 Posted April 16, 2019 Chuck the probe post turbo then? Im about to fit one of those gauges in defender, I've got the water temp sensor as well so I'm replacing the temp gauge in the dash with the redarc guy. I think it's worth the money, has nice features like temp warning, relay output etc. 1 Quote
Mof Posted April 16, 2019 Posted April 16, 2019 Came with the vehicle so I don't know how much. Goes over 700 I know that. Quote

manamari Posted May 20, 2019 Posted May 20, 2019 Looking at a 2001 nissan van with a zd30 with 320ks Internet says they're bit of a lemon Opinions? Quote
Casper Posted May 20, 2019 Posted May 20, 2019 In Nissan diesel circles the zd30 is known as a grenade Quote
manamari Posted May 21, 2019 Posted May 21, 2019 Yeah bought it anyway hopefully being a n/a it wont give me to much trouble (touch wood) Quote
Yowzer Posted May 21, 2019 Posted May 21, 2019 Ewwwwwww Might as well walk. It'll be quicker. 2 1 Quote
