Great video! Appreciate your time that you put into this. Lot of work.
Well done. Have been waiting for you to do the seals. Can't wait to see if there is an improvement in oil consumption.
Same for me looooong cranking after soaking the pistons with chemtool i take the injector fuse crank it again then take out the sparks plugs to check them was dry put the fuse. When the engine finally starts it takes likes 30 secs with pressing the gas pedal to normal idling. It was flooded with gas or the chemtool at the cylinders.
Hi I love to see how far uve gotten. I've literally done the valve seals a week or two ago on my 1zz. The car smoked even worse than before on the first start up. When I'm accelerating hard the smoke is now a Lil less but black rather than blueish. My valve seals were blue and brownish rather than green though, and had no ex or in on top to indicate where they went. I put brown on exuast and blue on intake. I did use more pressure than you did but I am a Lil worried that the valve seals have lifted from their sitting place and am going to go check it. I'll see how yours turns out before Goin back in. I will upgrade the pistons a Lil later on.
Ps, car still Burns the same amount of oil lol.
No dielectric grease?
Very nicely done. The seal will help along with the new gasket if they were leaking.
Good luck.
A great step by step video! Excellent content!
I'm really curious to see whether this will help a little or not, because from the borescope video a lot of the oil seemed to had come from the top, I think it was mainly in cylinder 3, the amount seemed to be too much to me although I'm no expert at all, but I think if that oil was coming from the valve stem seal then you should see a significant drop in oil consumption, since if that amount was continously leaking I think it would amount to more than a quart in a couple of months
But it could be coming from the spark plug housing or seal too or maybe it's all mainly because of the piston rings as everyone expects
Can't wait for the result video!
That long cranking at the end made me nervous. After all those long hours of great work, you don't want to bend some valves haha. But, once it's start running, seems to run fine.
Dave, I love your humble way of getting things done! Great job!
im betting rings
Great video Dave! Can’t wait for part 3.
I’m thinking the valve seals may help a bit, but rings and drain holes are the biggest culprit, just my opinion tho…
Ok here we go! I've been waiting to see this one!
Thank you . FANTASTIC camera work. I've never seen this done . I learned . I hope you dont die or anything so i can see the results. Oh, i guess , i could die… dont take too long on those results.. yah never know.
Good photography and explanation of what you were doing. Following this series with interest. Thanks.
