AS for cam bearing, it take special too to remove the and install them, some honing is need some time to fit the camshaft, some cheap cam bearings that have splits in them are the very worse and a nightmare to install and fit to size with the camsahft. Go with the Durabond brand for B series MG engines, great quailty, full circle, no splits, and come closest to not needing honing in most cases. If you rebuilding an engine, I do a engine rebuilding kit/service, where I help you thru the entire rebuilding proces via phone/email tech advice, and get you the better quality parts at good prices, I do these engines everyday, so I know what I like and don't like as for part quality. I make sure you get the good parts, you don't pay any extra for the parts, in most cases, less, and you get me for free for tech advice thru the entire process.

Most of today's aftermarket cam bearings come pre-sized. Occassionally the/a bearing may need to be honed a little to fit better. Also, sometimes they are a bit loose due to journal wear on the cam. It was much more prevalent in the past to have to line bore/ream the cam bearings to fit the cam journals. Not so much anymore. As Hap indicated, the split seam cam bearings are a pain in the backside to install. The middle one seems to want to twist out of shape the easiest and you can screw it up faster than you can say "MG". If one has a cam with a really worn journal(s), then some of the "non-sized" cam bearings may be the ticket to close up the clearances. Cheaper than welding up the journals and re-grinding.
Press them in and check the fit. Hone if needed.

Drove the CA 91, I-110, I-405/5, CA41/46 and CA101 a couple weeks ago. Went from San Clemente up to Salinas. Passed Buttonwillow exit and a couple of track day cars on the I-5. Sounds like doing the race car and Willow Springs would be a lot of fun. Especially with tracks that close. The oil wells in the Lost Hills were pumping away and they were drilling new holes. Guess we haven't really exhausted all that US crude after all. Really neat countryside. Visited APT and ISKY while I was out that way.

Dave, sure we talked yesterday, nice chatting with you.
I get the Durabond cam bearing at British Parts NW, they available for the MG B series engine, but not the Midget 175, on those engines I use AE, which is a full circle cam bearing as well, AE full circle cam bearings are als0 available for the MG B series engine as well, I use the Durbond in B series engines for two reasons, they are great quality, have great reputaion in other applications, and are a few dollar less tha the AE for the B series engines.
Don, I've been lurking here, just waiting for a interesting engine thread to come about, hey it's what I do everyday, so what I comment mostly on
