ok so in my 91 i was able to just pull the hose off the brake booster and suck it up there but im trying to clean out the 92 and when i pull the hose off it dies.. so i had a friend give it a tad bit of gas to keep it from dying. it sucked up a tad bit then it died.. the we restarted the car and instantly it sounds like knock..

is there something i did wrong?

 

I do not think I have seen a single thread saying seafoam is great, only issues.

 

You probably sucked up too much, hydrolocked, and bent a rod. The brake booster line is way too big. It could literally empty that entire can in a second if you motor is spinning fast enough.

 

I hope this thread is a joke.

 

it was running at just above idle.. and sucked up no more then .5oz

 

In that case, I have no idea. I can't think of anything else that would cause your car to stall and then suddenly start knocking.

 

and to throw out a new variable in the equation.. i just came back from pressure washing the engine bay...


i pulled my plug wires and found water on the bottom of the rear cylinder(1.6)

 

ok just pulled the plugs and found that cyl 1 and 2 are fine, 3 was covered in oil and a tad bit of smoke came out of the cyl, and cyl 4's plug was cold while the others were hot

 

replace your plugs and get back to us.

 

If the oil was on the outside of the plug fix the leaking cam cover gasket first.

 

ever get pics of that greddy.....?

 

ok new plugs are in, along with new wires..

knock happens at start up. then goes away.. but comes back in small bursts when i rev the engine and the shifter shakes violently..

 

ill get back to you with them soon.

 

Are you sure its knock? Or is it the common valve tick we get sometimes? I would get ticking upon start up and occasionally during revs. Once I did the 2twisty flush its been good to go ever since, and that was when I first bought the car years ago.

 

Sounds like the lifters if it goes away right after startup, good call Vash.

OP - next time use a much smaller line. Trying to seafoam (much less keep the engine running) by going through the brake booster would be like drinking a coke with a toilet paper tube as a straw.

 

Use the red one:

 

Probably more effective to put a few teaspoons down the plug holes (warm engine), let sit for 20mins, then start and rev.

 

ive never heard valve tick before.. is it loud like engine knock?

 

ive used the brake booster on my 91 with no problems many times.. i never stick the hose into the seafoam. just above it so that the sucking slowly pulls the water up to it

 

Nope... I still think you need to do the tdc test. See if all 4 of your pistons come up to the same height.
