What is this schrader valve you speak of? I looked for DIY compression injectors but found none

Think of a tire and valvestem.  When you put air in the valve lets the air go one way and not come out till you push that little stem down.  Same thing on a compression tester.  It keeps the first stroke of air you put in in the line and gauge so you are not always pushing it back in.  If I can get my tester out I will picture it and slap it in here later.

Reasonably clustered values, so no weird stuff.

Head off, photograph head face and piston faces.

Inspect top of bores for wear groove.

Sump off pistons out, photograph pistons sides, capturing ring gap positions, and any stuck in.

 Gently remove rings of worst and best chamber, and put them in the bore.
Measure/photograph gaps.

Have new rings to hand. See if a new ring will meet gap spec etc etc

Is someone pulling threads apart again by commenting, and then removing?

Quote from: 8v-of-fury
It is entirely possible, but it is not Lucas or I as moderators. Unfortunately people are allowed to delete there own comments and threads do get confusing. Name calling is not the way to go about it though my friends.


If you do as I mentioned it may be that a rering and hone by any method you choose, will be sufficient.  Without hunting, can you remind me what other issues you have other than seeming lt high sump pressure?
I think that idle blowby is often greater than operating speed blowby due to the time element, so things may not be as bad as it appears.

Erasing comments is within the rules of this forum. That type of comment was not. Check yourself there fella.

I clearly missed some intervening comments that passed on through the night hours :o,

I only recalled your comment about the valve which was completely innocuous. Can't you see how it messes up the threads and makes people look like they are talking to themselves? I also thought you stated in another part of the forum that you have only come back to sell in the vendors section, so I guess you have changed your mind. Welcome back if that is the case, or goodby if not  ???

No, there weren't any other comments that you missed.  Please leave the name-calling and insults out of your future posts, Mark.  If you want to avoid any discontinuity in the thread in the event that I delete one of my posts, then it would be most effective to not reply to my posts.  As long as the option is open to me I will continue to edit/delete my own posts when the mood strikes and for whatever reason I feel fit and how you feel about that is no concern of mine.  Similarly, where or when I post really is no concern of yours.  Thanks for the welcome/goodbye.

But you quoted his. I think this type of bickering to get a rise out of someone is not in the best interest of the forum. Have a nice vacation Mark, see you in a week.

Those posts (and the bits deleted by mods) were directed at Jay?  Jay is "CADman" and "He Who Must Not Be Named" and "Eraser", etc...  That just doesn't make any sense to me.

Deleting/editing posts
« Reply #14 on: March 15, 2012, 09:44:27 pm »
Letting people delete postings does a great disservice to this board. Many threads are just about worthless because of the discontinuity. People disagree and no amount of self serving editing will change that. It also allows people to hide what may be useful information as well as mis-statements. This forum would be much better served if no posts could be edited after 12 hours, like every other board that I have ever been on. The current practice allows someone to make and absolutely incorrect post and when called on it edit his previous posts to make the people who had it right look like the lame ones. I have seen this several times on this board.
