Last week my hack of a rally car started to tick excessively (has just had an engine oil flush, new oil, filter and a good dose of MBL-8). There has
been no lifter noise at all for 2 months after this service was done but all of a sudden the lifter noise started. I tried to do another oil change and
adding new MBL-8 but nothing fixed it. While it was quiet at work I removed the cam shafts and remove the lifters on the side that was noisy.
The problem is there are 2 different types of lifters in the head, one is solid and the other has indent for the spring and the spring sits on a washer.
There are 3 solid lifters and 5 "sprung" lifters. I would like to know which lifters should be in there and what ones should be replaced.
Thanks for the help
