valve stem seals quick question

[sho_stopper513]

its been awhile since ive been on here but i have a 93 sho 3.0l mtx. im getting ready to do valve stem seals and i had a question. i have searched and searched and can seem to find the answer im looking for. Q:is it possible to just zip tie the timing belt to the cam sprockets and just move them out the way or would i have to go about it another way? thanks any suggestions would help

Not sure what you are asking but I would say no. Why would you want to zip tie the timing belt to the cam sprockets??

 

[thundersho]

Funny Im about to do the same thing. Ive read at least 4 different how to's and all have you removing belt from cam sprockets all together. I would have to agree with no on this one. Check out this how to from jason aka yamahasho http://www.shophoenixproject.com/stemseals/stemseals.htm..

what im asking is would i have to tear all the way down to the timing belt tensioner and loosen it. or could i just pop the sprockets off and leave the belt tied to them.

clearly you will need to release the tension on the belt before you can remove it or the sprockets.

 

[sho_stopper513]

ok thanks i might as well change my front crank seal while its apart

im back lol getting to the timing belt tensioner wasnt as bad as i thought it was. but anyways, i changed my valve stem seals yesterday, an while my intake was off i notice a lot of carbon build up. so after putting the car back together i ran some seafoam threw a vaccum line on the intake and a little in my gas, but my car seems to still smoke after valve stem seal replaced. my question is how long does the sea foam take to burn out of the engine? if the valve stem seal were not the promblem wat else could be causing the smoke.
by the way the car has 123000 miles on it. an it is blue smoke so def. oil. i ran a compression test and results were:

#1=200
#2=195
#3=195
#4=195
#5=190
#6=185

 

[sho_stopper513]

well seafoam should be out of engine now and it still smokes. so i don kno wat to do. i really dont have the time to tear it back apart being that it is my DD,i guess craigslist it is!

 

[kevinspann]

How bad is it smoking? It is coming out of the exhaust?

 

[sho_stopper513]

it smokes at start up when car has been sitting for a while or when i start it in the morning and its smoke bad when i put my foot in it, but if i just cruise it real easy an not in it, it seems not to smoke as bad(very little).

also i just rememberd that when i was putting compressed air in the 2nd cylinder while doing the valve stem seals i heard a gurgle sound out of the intake port and can hear the compressed air leaking out . head gasket? valves? worn rings?

You can zip tie the timing CHAINs to the sprockets, then remove both cams at once.

 

[sho_stopper513]

yea i zip tied the chains but removed them one at a time,but that works too.

 

[rubydist]

typically these engines get sticky rings, which allow more oil burning at startup - the pistons are aluminum which expands more than the iron block when warm, so cold pistons are more loose - if the rings are sticky then the rings are too loose when cold.

seafoam will not fix that. autoRx may, or else using high mileage or diesel spec oil with more detergents may loosen the rings, or you may need to pull pistons to clean them up and/or re-ring them depending on how bad they are.

fyi, every SHO motor I have had apart (all 150k+) have basically had stuck rings.

also when i did the compression test on cylinder #1 it reach 200 but leaked down to 175 really fast and cylinders 2-6 did not do that.

 

[sho_stopper513]

well i wont be able to take the pistons out until next week but wat kind of high milage oil would be best. im running quaker state 5w-30 advanced durability now.

 

[sho_stopper513]

will marval mystery oil in the spark plug wells free up stuck piston rings if i let it sit overnight.
