ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:

    Expensive hit and miss experiance

    Ok well to start things off,
    I have a 1991 EXR 2 dr, when i first bought the car it burned oil and when cold smoked like a burning house, the minute the temps came up to normal operating temperature the smoke would stop, aside from the classic honda 7000rpm shift puff, so as time went on i decided that i needed to fix that polutionous problem, so my father and i thought we had it narrowed down to the cylinder head... which we then went ahead and swapped for one with less k's and pressure tested to be ok, needless to say it still smokes like crazy when its cold and stops when it warms up... weird... but now that the head is complete and swapped, all vac lines correct, timed properly, it seems to bog sporaticly, expecially noticable shifting into second gear, we have gone over several differant things and cant seem to find why its bogging and why its still smoking....
    does anyone have any input or possible ideas as to why it bogs and or why it smokes?

    any help would be greatly appreciated.

    Check your piston rings for wear? Do a compression test?

        Check your valve seals in the head or whatever there called.

          the head was pressure tested at 70psi, no problems with any seals...

          im not so much worried about the smoking as i am the bogging.

            Is the head for the same engine? I.E. Is the new head off an engine with the same block #? Because some heads had different camshaft profiles.
            The valve guide seals could still be shot even if it it pressure tested ok. They are pretty cheap anyway, a bit of a pain to fit, but worth trying.

            If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.
