I have been driving this rebuilt engine for about 3,000 miles now and it seems like it's burning oil more and more...it's usually at high rpm.........I know oil rings is usually what causes this but is their anything else that migh cause it to burn oil a high rpm it's just hard to believethat it might be the rings!!!

here is my set up:

stock block
new rings
used same pistons and rods
new bearings
used crankshaft

head:

crower stage 2 cams
crower springs and retainers
port and polish
stock valves [IMG][/IMG] [IMG][/IMG]

rings. or a messed up block (warped) cylinder walls.
take your block apart and have it decked and honed, bored and sleeved, whatever it is youll find out if you take it to a machine shop.
or just sleeve it anf get some aftermarket pistons.
thatll do ya good

 

I needed to know before I start taking **** off and see it's something else that migh be causing all of this.....<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by xthekidx &raquo;</TD></TR><TR><TD CLASS="quote">rings. or a messed up block (warped) cylinder walls.

anybody have any other ideas?

 

 

 

 

Did you hone the block to honda spec? they are cleffed anus about the type of stone and rpm you need to do it proper.

 

Oil comsumption is caused by oil from the crankcase or cylinder head going into the combustion chamber and burning. What are the seals that block oil from going into the combustion chamber ? Valve steam seals and your piston rings.

My first guess would be your rings didnt seat correctly for some reason. Improper break in or installation probably. Did you hone the block ? But dont go pulling the motor apart yet. Do a compression test and leakage test first and see how your results are.

 

block was honed not sure if it was honda spec tho<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Chuckles99SH &raquo;</TD></TR><TR><TD CLASS="quote">Did you hone the block to honda spec? they are cleffed anus about the type of stone and rpm you need to do it proper. </TD></TR></TABLE><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by lude98SH &raquo;</TD></TR><TR><TD CLASS="quote">Oil comsumption is caused by oil from the crankcase or cylinder head going into the combustion chamber and burning.

So, their is no way in hell it might be something in the head?

 

how was the motor broken in?

 

hard with 5w30 oil<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 98vtec &raquo;</TD></TR><TR><TD CLASS="quote">how was the motor broken in?</TD></TR></TABLE>

 

 

hahaha like instantly raced?

your suppose to drive normally and not go into high revs for at least one thousand kilometers or six hundred miles

i think thats what it comes to roughly?

 

tell me what you guys think about this thread!!!

proper break in methods include going to the dyno the day you start it. Hard breakins put more pressure on the rings and make them seal better. Better ring seal = more power.

i told my automotive teacher that its better to break it in hard and he laughed at me

 

laughed because you were wrong or laughed because he doesnt know any better?

 

Well, I have search and searched and this is what I came up with...........when I rebuild my block again which thats probably what I'm going to do....I will not break it in hard....... until I get it dyno tuned, might start it up and drive it for 100 miles and rev it to 3 rpm for 5 minutes and then 6rpm after 100 miles and of course oil change after the first 30 miles and then after 100 miles

What you guys think about this?

because he doesnt know better...he thought i was wrong. generally they say to be really easy on it during break in

 

Do a compression check and leakdown. If you're still losing oil after a bottom-end rebuild. The next place to turn to would be the valve seals.

 

you know what? I will do that tomorrow!!! I got nothing to lose.....THanx guys

 

it be nice if it was just the valve seals!!!!!!
