So I started my truck up this morning to head to work. Everything started fine and when I was about 10 minutes away from home my truck started to bog down and then it died. I had lost all power. I tried to compression start it while I was still rolling but it wouldnt start.

I was able to get to the side of the road and tried to restart it. At first it wouldnt do anything then after 2 minutes of sitting it started like nothing was wrong. But this time I was blowing lots of white smoke out of the exhaust. Something this truck has never done before.

I started back off to work and it did it one more time. I ended up taking the carb filter off the carb and let it run free air as I thought it might be related to the carb.

I turned around and made it back home but am now stumped as when it was dying and blowing lots of white smoke.

Any ideas would be awesome.

Ive got a 85' 22R with a Weber 32/36 carb and no emissions crap.

 

There are 3 things that will cause white smoke.

1. Water in the cylinders usually caused by a blown headgasket. Check your fluid level in the radiator.

2. Bad idle control valve on the power steering pump allowing power steering fluid into the intake. You are carburated so you don't have this.

3. A combination of a bad brake master cylinder and booster. The master will leak into the booster and the brake fluid will destroy the diaphragm. Your brakes will be very hard then the peddle will hit the floor when there is no fluid left.




There is a 99% chance its #1.

 

Well I would be suprised if it was #1 because I just replaced the headgasket like two months ago and completely went through the motor and cleaned everything.

But besides the white smoke what would cause the motor to bog down and then die?

 

A hole in the timing covet due to a broken timing chain guide will do it also. Same with a corroded water port in the head.


Have you checked the radiator level yet? I've had head gaskets last less than 2 months.

 

yea everything looks good. brand new timing chain aand cover too

 

Pull your spark plugs, what do they look like.... I'm for #1 as well.

 

Yea kinda sounds like head gasket I had one last one week turned out my oem head 170+ miles corroded out . Coolant jacket ....things that would cause the motor to bog would be a rush of coolant entering the combustion chambers and killing the combustion process < white smoke what is normally the result of that sweet smelling steam/ muddy coolant/ milky oil

You can run the motor warm it up turn it off pull the plugs then turn the motor with the starter you may see coolant shooting out of the plug holes ..I did this and shot coolant out < head gasket time

 

so it is a blue ish tint to the smoke and it is bad smelling. When I popped the hood and let it idle I am now blowing smoke out where my header meets the two pipe down pipe. Like the headed bolts to the motor but is only a foot or so long. then it bolts to a downpipe. Im blowing that same color smoke out there too.

I dont understand it. The truck was running amazing before I changed the oil pan gasket. Now its blowing tons of smoke.

 

What do you have for exhaust?

 

stock. have never done anything to it

 

So what did you use for a oil pan gasket you make one rtv or use a gasket ?
Two peace header leaking . Just get some new exhaust donuts for that part should stop it

So you have plenty of power ? has the truck died on you again ?
Have you checked your weber carb and settings

 

Did the exhaust note change? I'm wondering if the muffler came apart and is causing major back pressure hence it running like crap and the major exhaust leak at the manifold all the sudden.

 

i havent lost any power. I just lose power when it starts to bog down.


It was just an RTV gasket but I ckeaned that all off and did a gasket with a little RTV as well. It stopped leaking but now all this started to happen

 

I no first hand that blue rtv smokes blue and smells like death when combusted in the motor but I don't think that is it

What about fuel filter check clogged or decomposing
Lean gas mixtures will smoke < obstructions

Have you reved the motor high yet does it clear up or get worse at idle or when revving it

 

so i went at looked in person at it today.

imho its a bunch of lil things adding up to something big.

there are more then a few possible bad vac leaks, a vicious exhaust leak at the collector flange and a known bad cyl.


so im thinking that he's got a clogged cat from the truck not quite running right for a long time(before him). and a possible failed new headgasket because it was not resurfaced.

gave instructions to fix all the lil $hit, install a test pipe for "test" purposes and re-torque the head to 90-5lbs in stages.

at that point its about as good as gets for this motor, there is a knock sounds like #4 rod is knocking and its time is running out.


only other things i noticed were the oil was a odd grey color, no metal so maybe fuel through the bad cyl rings or exhaust blow by and murky looking coolant, not oil but not clean looking either maybe exhaust or just left over gunk from time.

 

Ok cool good deal going to check it out for him maybe time to consider a fresh rebuild

 

It sounds like the motor does need a rebuild as well. It sounds like cyl 4 has some bad rings in it if your getting blue smoke? I'm not the most car savy but i do know blue smoke is oil and the white is antifreeze generally.
