Hey guys, i've been working on this b18 for a couple days now. It was dropped off to me by a friend that wanted his car to be running properly again. It's having some problems that i will explaine in the notes that i've taken & pasted in below.

11/28 - 6:30pm
Come home to car
-start car / pull into garage
-very rough sounding
-pop hood & listen / sounds like valve trane troubles
-nasty vibrations & loud engine running noise that sounds like it's in the
head
-put hood down to take for test drive
-release e-brake & rear brakes feel like they are sticking
-check front brakes b4 test drive & they seem to be alright but weaker
than
normal

11/28 - 6:45
Test Drive

-very weak
- RPM range doesn't seem to utilize cams properly
-grindy feeling / no real varriance in power
-put back in garage / waiting to cool before i pull the valve cover to
take
a look.

-COMPRESSION TEST-
Cylinder4 - 185
Cylinder3 - 180
Cylinder2 - 180
Cylinder1 - 190

looks good to me!

Next

Pulled valve cover (where i noticed u were missing a nut due to broken off
stud)
- nothing appeared wrong or bad to the point of being able to see it
-valves seemed a lil tight so i gave it a valve adjustment job & put them
back to spec. (for now)
-got a slight bit quieter
-erratic idle continues

Test Drive
-still weak / almost sounds like bearing failure in the bottom end

Back in Garage
-let engine warm up till fans kicked on
-disconnected IACV & everything remained operating the same.. i would ave
expected it to change (thus, it could be bad)
-just for shits & giggles i took the alternator belt off coz i rememberd a
situation i read about before where it sounded like engine noise but it
was
actually the alternator pully bearing .. really freaked me out coz it got
quieter.. still noises tho...

I'll tackle some more tomarrow.. afraid to tell u that the oil pan will
have

to be removed to check out the status of your crank next.. if i don't see
anything then the next step would be to pull the head & look to see what
messed up parts i run across! Another sound that could sound similar to
the

DAY 2

I've begun to tear this thing apart to search for destroyed parts or metal shavings or what ever i could possibly find that would be noticably wrong!

I could go step by step but heres the quick notes.

- NO metal shaving in oil pan
- Bottem end bearings appear to be functioning properly
- Top end on the top of the head looks good, no bad worn parts or anything noticable
- possibly valve issues, you can look at pix
- i examined the top of the pistons very very closely & you can barly see any type if any of a clean mark on a couple edges (pushing tword head gasket but it's very hard to tell)

heres the pix

DISCUSS!
