13B-T rebuild needed

[cicak]

Tuesday - nightgave my Red truck to the employee while I took the Isuzu for a service and Would drive it baCK up saturday morning.

Wed arvo I get a call Dad at rawang service station 30 k from my house RED is making bad noise and smoke from engine.

The rawang mechanic went and had a look rung back Towtruck its bad meet me at my workshop. 2 hours later I give the employee my isuzu and away he goes.


Then we lift the tappet cover no damage phew.

we have dinner He he gives me a lift home I will take head off saturday and call you Monday Im away for 10 days .

Monday I get these images





I have a spare motor on the workshop fooor with no head.

10 days to wait before rest if damage is known.

Cause we think ring went as puffs of smoke seen coming out rear by a 1kz owner the previou week as he tried to keep up.

Some observations, what is the history on the motor? How many kms? Servicing and oil use? From all the marks it kind of looks like the piston has picked up in the bore, excessive EGT's, or poor cooling?

Piston oil squirters still working? I ask because I recently had the sump off my 13BT, ~70,000kms since rebuild, uses 15W40 oil at ~5000km intervals and the underside of the pistons are still bright and shiny and the bores look good too. Your pistons appear to have coked oil on the underside.

good question we are going to look at it all when the rawang doctor is back and see i the piston oil squirters are workign as it was my first suspicion.

Engine was rebuilt in 2008 completely.

It was starting to use oil so I knew I had an issue.

EGT/Boost gauge and water temp (all apexi) and stereo (over $2000USD worth) all stolen while in a workshop and replaced with a $300rm stereo and a BOOST gauge only (roughly $150usd all up) . After the next rebuild I am replacing the gauges again and also an oil temp gauge however all this expense while trying to reuild the Volvo I do not need . The INTERCOOLER seems to have kept the normal cruise engine temps down there is a bigg difference before and after the INTERCOOLER installed to the engine gauge temps.

Has never used COOLANT in the 5 years at all.

I drive this engine hard very hard so it is possible that that and if the oil squirters failed then damage may have occurred. Nothing unusual for me to sit on 120-130k for 2-3 hours in this truck its qute happy at these speeds and so is the engine temp etc.

As for the Russian newbiews comments I am totally ignoring him he is a trouble maker (supposed language barrier or not) he ain't here and ain't driving my trucks.

Maintenance has been done regularly including oil changes and oil filter changes and Diesel filters and injectors (every 50k here at least).

I do suspect overheated oil also as the starter has now started to not start sometimes until the air cond is turned off implying solenoid is possibly gone due to excessive heat

More in 10 days time when we strip the spare engine down and the engine down and start analyzing what went wrong.

Oil temps would be a interesting thing to monitor and check against the oil specifications for the temps that it starts to break down. When working on mine, at idle the sump got to hot to touch due to oil temps.

Not having much luck are you! Bad to have one vehicle go....but two!


That broken piston reminds me of a HVAC compressor keep having to have repaired at great expense. The conrods and piston break because oil has been leaking into the combustion chamber. Now have to install an oil separator.
Not the same as a diesel engine, but the damage is remarkedly the same. So I was wondering if the 13b had some how had unburnt fuel in the chamber.

Are those pistons the originals or were they upgraded during the rebuild or build? Recall you were considering doing that.

New pistons, Rings, sleeves and bearings total rebuild done

I am inclined to blame this on the mechanic who did the rebuild. Whether it is his fault or not something must have went wrong when rebuilding. These parts do not look like they were installed recently.

Rebuild was new, as post above. Depends on the km/miles done since the rebuild. 5 yrs is a long time. The original engine was quite low km to start with.

I would and will not blame the mechanic the rebuild was complete strip and rebuild 5 years ago. I have driven this Vehicle everywhere hard and soft and to excess possibly a low oil situation one day when it was almost vertical or sideways may have caused damage which has taken time to show up. We will check evrrything during the strip.

Yes going to install oil temp gauge

I agree the SUMP gets damn hot.

I am going to install a oil temp gauge this time around after making sure it will not be broken off by whatever I encounter in the jungle.

I also admit I drive this truck hard and have done many hill climbs in 4 LO when everyone else is struggling in 2 LO or 1 LO and it eats the climb.

Maybe I need to install a oil cooler.

Inspected block today and piston wow looks like only one piston failed rings and piston ruined it was not low or Oil as, had checked 50K before giving to the employee to drive. Bore has 4 holes or score marks in it. Oil squirter damaged by busted piston.

 

[Radd Cruisers]

Looks like it got pretty hot.

What are your EGTs?

John No EGT my mistake I never replaced it.

"EGT/Boost gauge and water temp (all apexi) and stereo (over $2000USD worth) all stolen while in a different workshop (2009) and replaced with a $300rm stereo and a BOOST gauge only (roughly $150usd all up) . After the next rebuild I am replacing the gauges again and also an oil temp gauge however all this expense while trying to reuild the Volvo I do not need . The INTERCOOLER seems to have kept the normal cruise engine temps down there is a bigg difference before and after the INTERCOOLER installed to the engine gauge temps."

I'm going to install in a POD with EGT, BOOST, Water temo and Oil temp probably replace the altimiter pod with my own custom POD which I will start in the coming days. KInda busy next 3-4 weeks as have 2 TV crews doing video's of our riverboarding business this weekend and two weekends later.

Still trying to analyze why only one piston failed the rest look fine will get the others next weekend and inspect and take pics also.

I've seen a big old Nissan UD do something like that, it overheated and boiled over until the driver noticed the overflow bottle steaming and pulled over. One piston was completely destroyed, much like the one above, I think the others were mostly intact

Coolant never had to be topped up ever was very good can only assume temp gauge being factory may not be accurate enough

Pistons, Rings and Liners ordered from SABAH Arrive monday or tuesday.

Looks like it was a squirter failure from the discussion with another mechanic proably the squirter broke off.

I hope to have it rebuilt and back on the road in two weeks along with a host of gauges fitted this time.

Picks of the damage.

The clutch needs to be replaced 100,000K and the GOD winch and the excessive power has taken its toll.

 

[gotoy]

Time to get your self an extra heavy duty clutch from exedy.

 

[BobBJ74]

Are the liners your using a finished or semi-finished liner? Had my 13B-T rebuilt a few months ago, work shop said they could only get semi-finished liners. So the new liners have to be honed out before you fit piston. Was this the case for your rebuild?
