Truck: 22re 1990 2wd

What: I just did timing chain with metal backed guides from engbldr at 128k. The ones in there didn't look bad at all but the previous owner (my dad) never did any maintenece so I figured I'd just replace them. I put in a new water pump and new hoses from Toyota. Also used a new front cover from the engbldr kit. Used all new gaskets, except for HG and oil pan. For the oil pan I used Grey Gasket Maker. HG left as is. New oil and filter.

Then? Started up fine, did timing, flushed coolant, new Toyota red (don't know what was in it before). White/blue smoking coming from tailpipe! First thought was burning coolant, but then I figured maybe it would go away. It did.


PROBLEM: I drove it around after I got the timing right and decided I'd adjust the valves. I took off the valve cover and I find some milky stuff. This is not good. Coolant + Oil = milkshake. Milkshake = bad. I check the coolant (my new $15 gallon of Yota red!) and I find some brown/red stuff. Brown coolant = also bad.

Conclusion: I am thinking about changing the oil and flushing the coolant (again). Perhaps this will fix the problem. But, I am afraid that the HG did not seal, and hence the all bad milkshake + brown coolant party.

Perhaps when the front cover was re-installed? I am quite sure the gaskets went one correctly.

QUESTIONS: Any pointers on what I might have missed or what I can do to fix it? I tightened and double checked everything (I'm quite sure). Truck drives fine, and it even has new thermostat (This fixed the previous "temp gauge never going up" problem).

Thanks a lot Yotatech members, this board rocks.

Do a compression test on it, see what kind of results you yield.

Zetoe

I did the compression check and these are my results:

#1: 160
#2: 157
#3: 152
#4: 160

This was done on an engine warm enough to touch. What does it tell me?
(I didn't have a helper to tell me how the guage goes up or whatnot.)

Zetoe

Any more suggestions?

Thanks for reading!

Yota4runner

In my opinon, chances are since you tried to reuse the old HG that that it didn't seal properly. I would start there.

Zetoe

Went down to Toyota Deaership and asked their parts guy.

Old coolant = green
Old Green + New Red = Brown

Doh!

It sounds like the timing chain cover has a hole worn in it from the chain hitting the side. It might be very small, but when under pressure it pushes coolant into the oil passage.

I have fixed 2 of these personally.

Yota4runner

I do believe he said he put a new cover on.

I would'nt ask the parts guys anything other than parts. It seems like every parts rep. never knows what they are talking about unless they have a computer and the part number in front of them. Our own parts guys don't know squat unless you start talking about Mustangs. I'm not too sure about the 2 mixing and it turning so quickly, but I've not experienced that in my shop so it can probably happen. The only other explanation is that you didnt let the gasket maker dry overnight and/or as yota4runenr posted you tried to reuse it. Did you properly torque them and in the right order?

CynicX

Parts guy is probably right. Not only will mixing red and green make a brown color, there chemical make up is different. Mixing them together cause it to turn into a gel, a brown gel.

When mixed this new chemical is very hard on the coolant lines or so I've heard. It will eat them up pretty quick, so its probably not good for anything in there.

I'd flush it out with water until its nice and clean, then do it once more. Possibly even have it flush with one of those machines that pushes everything, but I imagine the old fashion way will work. Then add your coolant again and check it again.

If air cant find its way out of there then I doubt coolant can find its way in.

To add to that post when I say flush I mean pull everything compentant apart and flush it out with a hose. Radiator, heater core, etc etc so you get all that crap out. So it doesnt keep doing it.

Mid to late 90's Blazer, Bravada, and Envoy's had a problem with the coolant turning into that milkshake/mud (something to do with the coolant on a certain type of metal) if you werent good with the coolant maintance. The only way to clean it out was to pull everything apart and flush it out.

superjoe83

did you remove the head without replacing the head gasket? your post does not clearly state that, and did you make sure that you got every little trace if gasket off the block before putting the cover back on, my friend did a half a$$ job doing a chain and had the same problem, water in oil, but if you did reuse the head gasket then thats most likely your problem

jimbo74

putting a new cover on has nothing to do with the chain eating a hole in the block

Zetoe

I did not remove the head. I only took off the front cover. Thanks for all the replies. I'll flush the coolant in the morning and hopefully fix the problem.

milkshake oil could mean you picked up water from wheeling or otherwise. not nessarly from the coolant.

i like the green+red=brown for the coolant.

change both and see what happens.

Goots

Did you have a milkshake before the timing chain install? I am dealing with that now, and that stuff was all over the place. Had some even stuck on the radiator cap. Try flushing all and see what happens. Keep us posted on the Rx.

surf4runner

did you change the oil afterwards? if you got coolant in the pan during the R&R of TC, a nasty milkshake could appear. change/flush both and start w/ water to ensure that a(nother) seal hasn't failed. drain water add coolant. check torque settings.

Zetoe

Changed coolant and all seems well! Thanks for all the help guys, I was sure freaking out. Aside from this little scare, TC wasn't hard or bad at all.
