Hi CA gurus

I recently picked up a RWD CA18DE with what looks to be a factory silver rocker cover. I've only ever seen red ones though?

Did they actually come in silver? Does it mean anything? Year model?

Cheers

I doubt it would mean anything, ive only ever seen red ones and no body has made noises about a "silver top" one by now so i figure there is no difference

may be a CA16 valve cover, i think there were silver tops to those in B11's etc

I have found out it means I was just sold an engine with at least one spun bearing........

Started it up on the shed floor today and heard a nice "tap tap tap" above idle RPM (insert swear words...)

Time to pull the sump off and see what carnage awaits. If I luck-in and crank journals are OK - where do I go for new CA bearings?

my engine has acl race bearings, most people seem to use them on basic rebuilds of performance stuff.

if its spun the bearing you will have to get the crank reground and rods resized. otherwise it will just spin again

been there, done that. got less than 5 mins driving before it spun again

yes if it's actually flaked or spun then you'll need the crank out

if it's just knocking you may get away with it

oh and to the original where do i get bearings question, i just got some normal ACL bearings from the local auto parts place. went race series when i actually rebuilt the engine though...not really worth the extra money in your case as i'd say they wont be lasting very long

Thanks for the advice. Seems when it comes to buying condition unknown engines - You win some, you lose more....

Its a spun big end on #1.

We believe that the cause of death (injury actually - death is a tad strong) is that someone ran the engine either without oil or with very low oil. Cylinder #1 is first stop after the oil pump, so if the oil pump took a gulp of air - Cylinder #1 would be the first to spin dry. Sound feasible?

The big end bearings don't even look that bad considering the trauma they've endured. You can see the scratch mark across the left one, showing where the right one came to rest after it spun.

Anyway, after removing the oil film from the crank journal there doesn't appear to be ANY scoring of the surface - so I will gap up a new pair of bearings, throw them in, and call it fixed for now. Lets face it, its a 60,000km old $250 engine (inc ecu & loom) so no point spending big bucks on it - without at least trying the cheap fix option first...
