Hello all , merry xmas!! i just got a head job on my 87 toco efi 4x4,not sure what motor,2.2 or 2.4..and now im smelling oil out the exost.that isnt normal is it? any kind of quick fix i can do..
ps. the head was shaved 50 thousents of an inch..

It could be a blown head gasket (part of the "head job") or it could be worn rings - do a leak down test. I think 50 thou is a pretty big cut in the head - was it badly warped?

It's probably a bad valve guide seal or two. I bought a rebuilt cylinder head from cylinder heads international and it ended up having bad valve seals, so I had to do two head jobs because of someone elses stupid mistake and because they don't check their cylinder heads for errors before they are shipped out.

Does it only smoke on startup?

a leak down test , is that the same as a compreshion test....and will synthetic oil help my rings ???

ToyYoda

A compression test measures pressure in the cylinder and a leak down test measures pressure loss. Here's a good article on what exactly a leak down test is. http://autos.yahoo.com/maintain/repa...ques057_1.html

Synthetic oil will cause a disaster in older motors with older seals. I tryed using synthetic in one of my higher mileage vehicles and had oil leaks from everywhere. Some people say to run synthetic in the motor for 3k miles twice a year, then switch back to regular 10w-40 or whatever you use but it is great stuff and definitley lubricates those tight places in motors.

They sell oil additives that help restore rings but there's really no fixing worn rings unless the motor is rebuilt but I'm thinking it's probably related to the cylinder head.

stop playin in the mud and it might be worth it. i loved muddin until it screwed up my brakes, balljoints, and a cv.

Then you have a blown head gasket. Take the cylinder head off, get it tested for warps and valve problems, buy a cylinder head gasket set if the cylinder tests OK and go to town. Older Toyota 4x4s are definitley worth spending the money to fix. They are badass trucks and have cheap parts that are readily available. If you are a DIY mechanic like me and enjoy going offroad, then owning an older/less expensive model yota is the best way to go.

Take if off-road and enjoy it but expect stuff to break. Fixing stuff should be part of the fun

thats just the ting i just got the truck back on 12/21/06 from having a head gasget put on and having the head shaved and a new timming chain...if there is a new reboult head , can that make the rings go out????
and yes i will keep my toco i just love driving around the fords chevys and dodges!!!!:bigclap:

ToyYoda

Do you see smoke or only smell it? It's hard to tell where it's coming from or what's causing it without knowing that. It could be the rings but I don't think so.

hogie9ll

i see the smoke right out the tale pipe , blue smoke smells like oil and befor the head job there was no smoke it still uses oil about 1 1/2 quarts a week..i did a comprtion test today and number 3 plug had oil on it and the test was only 90psi..i think the rings are bad!!!

ToyYoda

I had that happen to me and it was the cylinder head.

Does it only smoke on start-up, then clear out as you start to drive around?

hogie9ll

yes blue smoke when starting up,,,after warmed up it doesent smoke...one more thing my machanik (sorry 4 the spelling),advancecd the timiming 3 degries ,so i think it set at 13 degrese befor top dead center....if i had a shed i could do the dam ÅÅÅÅ myself

callmej75

Sounds like a valve seal to me..

hogie9ll

my truck i still blowing white smoke in the mornings and blue smoke when it idels but no smoke when im driving...only when it sits at a stop sign and hit the gas the blue smoke comes out...going to get a leak down test next week nd go from there,i hope the head shop f#$% up!!!!!

hogie9ll

ok just went outside and had my son hold up a peice of wood next to my tale pipe and i hit the gas when he didnt now it!!! HAHAHAHA and there was black sut/oil on the wood!!!!could that be from a bad head job ???

hogie9ll

well just got home from work and found no oil on the peice of wood , it seems to be carbin bould up, i hit the gas hard and black smoke came out my exohst.....could this be a mixture isure???
