Title: Dumbo needs help again
Post by: MAX Carpets on April 14, 2012, 01:28:49 pm
Hi Guys

As you knoe by now I am pretty much useless!! I'm having a bit of a problem with my Blazer plus. I hope this makes sense......

Above the blower there is a cylinder tank, coming ofthe tank there is a pipe that comes out and splits in two and goes in the back of the engine. Where the pipe joins the cylinder I seem to have sprung a leak, I have checked the gasket on the join and it seems fine, so I'm thinking hair line crack maybe?
Has anyone else experienced this? Can it be welded? If not, does anyone have one kicking around? If not what is the pipe called so I can have my account emptied by PROCHEM.

I hope this makes sense. Once again, many thanks in advance for your help........again.

Regards

Justin

I will try.  Not sure what the large cylinder is called. It sits behind the engine, on top of the blower.

Sorry, I know I'm thick.

Hi Mike

No, not water box. It is a silver/metal cylinder that gets extremley hot. I reckon that might help.

When I say sprung a leak, what I meant to say it is loosing oil from this area.

Sorry

Heat Exchanger??

It's the pipe from The heat exchanger cylinder into the engine.  Where it joins the heat exchanger it is loosing oil, I checked the gasket looks fine, so I'm thinking its cracked.

It is the exhaust heat exchanger, but it is only hot engine gas, not oil.

Simon is right, it is infact the exhaust heat exchanger unit.

Have you just topped up the engine oil? Could it be a carryover to the exhaust?

no i havnt topped up oil?

It is highly unlikely that it is oil - far more likely that the engine isn't burning cleanly and the dirty exhaust which has a certain amount of vapour in it is dripping out of the pipe.
Take a picture of it and post it on here.

Gonna get some pics on ASAP. The thing that caught my attention was the strong smell of burning oil and smoke coming from the join. Would this still match what you are saying?

Perhaps the engine is just burning oil with the rings wearing. What colour is the exhaust?

Yes.
Check the spark plugs, if they are dirty it could be a carb problem. Check the air filter. Dip the oil, make sure it isn't over full.
Your best asking Richie on truckmounters, he's run Blazers for donkeys years.

This may sound like a silly question but, I have just de-scaled the machine, could this have any effect?
Title: Re: Dumbo needs help again
Post by: Simon Gerrard on April 15, 2012, 01:26:25 pm
No. The heat exchangers take heat from the engine exhaust and just like a kettle element crosses the heat to the cooler cleaning solution and so the two never touch.
your problem seems to be dirty exhaust gas.
I'm assuming the water in your water box isn't dirty?

Try removing the air filter

Check the gaps on the spark plugs, make sure the elctrodes aren't warn out.
Can't see a picture

Friend has just done a compression test, low on one side. Said he thinks its the head gasket. Does this sound about right?
Title: Re: Dumbo needs help again
Post by: Simon@arenaclean on April 17, 2012, 10:03:11 pm
Could be valve or valve seat, maybe need re-seating if they are pitted or scored, that is generally what cause a drop in compression. Change head gasket any way but check valves at the same time.
