MG TD TF 1500 - Best source for quality valve lifters

I discovered that there is a lot of wear on the face of my valve lifters after pulling the head for a blown head gasket. An experienced mechanic friend inspected them and suspects they were from the batch some years back that was not properly hardened ( the engine was rebuilt about 12 years ago and has about 13,000 miles on it). Everything else in the engine shows little to no wear consistent with the low mileage. The cam lobes seem fine, thankfully. Does anyone have a reliable source to recommend for quality lifters that are properly hardened?

Brown & Gamons has some that are suposidy lighter than moss, but I don't know about the hardness.

I look at this briefly as I am rebuilding my TD/C engine. Peter Edney sells several sets of lifters. Standard and one oversize, an improved design for increased oil flow to reduce wear, and a lightened set for race engines which are intended to run at high RPM. The improved oil flow design was attractive to me.

I decided to have my original lifters refaced by Delta Camshaft and they new again. I'm changing from the uprated valve springs which were originally in this engine and going to use the standard springs to limit the pressure on the lifters and increase their life.

I second Charlie's comments about Delta Cams... they do a wonderful job re-profiling and re-hardening lifters, as well as nice work on cams, too. Their prices are also probably the best you'll find. I had them do the cam and lifters for the Sunbeam Alpine engine I did a few years ago... turned out beautifully.

Important though... breaking in new or refurbished lifters takes a special procedure and lubricants... carefully read the instructions you get and follow them to the letter. Delta includes the instructions with every job, as I assume others do as well.

Kevin, about what is the cost of having them redone? Thanks. Larry

Larry, I don't recall - it's been several years since I had the work done but I remember them being amazingly reasonable. You can just give them ring and they can tell you (800-562-5500)... they were very willing to help when I last worked with them. In fact, although I sent my cam to them for re-grinding they called me to tell me my cam didn't really need re-grinding as it was still in-spec and that it only needed to be Parkerized... saved me considerable money.

My finished Alpine motor, BTW... electric overdrive, too... runs really sweet.

Kevin McLemore

Thanks Kevin. I'll check with them.
Nice engine!
Larry Brown

Just gave them a call. Nice, friendly, cheaper that I thought!

If you read period literature xpag's have been chewing through lifters since they were first introduced. Long before the hot debates about zddp, etc.

Curious what type of valve lifters it is that are going to be "re-surfaced." Are they flat tappets or something else to match a cam? In the past they were sometimes cold hardened and sometimes parkerized. This sort of hardening usually just effected to "surface" of the metal, and not very deep in at all.

This is the best lifter!

Len Fanelli

I'm sure those are the best valve lifters / cam followers, but can they be used with a standard cam and pushrod set up, even if it doesn't get the best out of them?

Not if the lobes are chamfered! On a completely flat lobe, you could probably do it but you would lose a lot of power through duration reduction.
Steve Simmons

Ok, that makes complete sense.

Roller lifters can not be used on flat tappet cams

Anyone know the time-frame on the infamous Moss XPAG lifters?
