Reply With QuoteHooked her up to the laptop and she has 930 hours i think 55% at 800rpm it was set to XD100 oil and i have blue oil in the container do u think this was the problem it blew?
Yeah i hear u Noel if i had the cash tomorrow i would be off on Monday dropping off the E-Tec parts and placing a order for all the bits and pieces, i snagged that E-Tec while i have the opportunity and cash and i tore in to it a little early just because it was playing on my mind if it were repairable or if i was going to have to part it out and save for another engine, i have a bit of coin coming in but i don't know exactly when but hopefully within a month or two max
the boat is the biggest project and that's why i allowed 5 years to do it because i am learning as i am plotting along, the engine is a piece of piss to rebuild it just comes down to what i have in my pocket for that day financially
i have the boat on a trailer so that will likely be the last project is building the new trailer
the other boat i have the smaller runabout is probably a 1-2 day job tops i could probably get that done in 6 hours if nothing is seized or snaps, i picked up the gasket kit yesterday for that job
those are my only projects i would like to fire up the tig machine and weld a tank but that may need to wait untill i get my floor down in the boat just to get final measurements
I'm not stressing about the E-tec, little stressed about the stringers and bulkheads in big boat but i was stressed about doing the transom and i knocked that over easily enough, the alloy trailer should be a piece of cake to build and the little 50hp mariner doesn't really worry me i am just hopping the ebay seller sold me a good powerhead as i seen they are selling a conrod that fits my E-Tec and its a shady deal shagged to the s... house and they are trying to sell it

Whats your thoughts guys?
Can't say for sure the oil was the cause but I do know that if it is set to XD100 then that is the only oil that should be run. It has definitely been run hot at some stage - there should be a temperature profile available that will show a breakdown of how long at what temps. It's reading a max temp of about 100 degrees C - the alarms start chirping at about 90 from memory. The EMM doesn't look like it too hot though which is good.
code 71 and 72 BOOM
seems to have done a lot more hours at 5-5500 than say at cruise speed of about 4500, is this normal to flog out a etec.
maybe old mate put wrong oil in , had a brain fade, happened to me once blew my hydralic seals by putting in red instead of clear.
Yeah i have read if its set to XD100 oil that's the only oil it can use, idon't exactly know what happens if XD50 is used in a case like thisOriginally Posted by scottar
Nah mate those codes are only reading because i have the EMM and wire harness off the engine and most things are unplugged
Yeah i thought this engine may have been a twin 130hp on a big 28 footer cat or something that is why it reads high hours at 5000-5500 big boat easy to flog it home on a hot summers day after trolling at idle for marlin for 10 hours, I'll break down the seconds into minutes now
RPM, Minutes, Hours
800, 28256, 470h
1200, 6138, 102h
1600, 5786, 96h
2000, 2036, 33h
2500, 2649, 44h
3000, 1199, 20h
3500, 652, 11h
4500, 716, 12h
5000, 2154, 36h
5500, 2802, 46h
5800, 787, 13h
6000, .45,
6200, .6,
7000, .015,
on the hours i dropped the decimal off and rounded off to the closes hour, i only just realised looking at my screen shots i could look at EMM temp etc.. i will connect it tomorrow and check those settings
Also check the historical faults.
Thanks Scottar i just checked and it looks like the engine spat out a code right before it blew up i am so glad i have finally found the problem
at 924 hours (it has 927 hours on clock) it spat code 59 this is 3 minutes before it blew up, the code is the starboard cylinder failed to reach operating temperature so basically the engine had a cold seizure, the piston bit the wall causing the rod to snap and shit to go everywhere
bloody hell a $15,000 engine and this owner never changed the thermostats that's just crazy
I wouldn't read too much into that Gazza. Mine ran cold due to a thermo not closing properly for a long while. When they were replaced it started overheating at high idle until I fitted thermo's that were out of the Ficht engines that opened 10 degrees cooler. From what I understand, low temp is mainly a concern at low RPM. At high RPM's the thermo's do very little as the PRV is opened and is supplying most of the cooling.
Yeah maybe Scottar but when u have a cold engine and your flogging a hot piston in a cold sleeve i think this might just be the problem
Bloody hell ay not to sure now, temps are fine, the engine had oil because the top and bottom bearings were fine, no oil pressure faults, no fuel injector faults, i'll have another look at the sleeve tomorrow to see if there is any scoring
Whats the chance of sleeve fracturing from old age?
The engine was running at 5200rpm for 15mins i think before it let go i will post those pics tomorrow
Engine temps show it let go at 58c i will need to look into running temps
