2 different lifter types in the same head?

[1989RS]

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

Hmmm am pretty sure the ones that are standard are the ones with the springs because ive heard of people "upgrading" to solid lifters, could be wrong

id have a look at the other bank and match them with the ones in there.

sounds like its had noisy lifters previously and someones swapped them out with ones theyve had out of a different ej20

Thats what i was thinking, but i rang genuine parts and they sell the lifters with the springs. Also i have pulled apart a set of reconditioned heads i have lying around and all the lifters out of those heads are solid. It left me pretty stumped.

The ej20 engine comes in many, many different forms due to its vast use throughout the subaru range for well over ten years, over that time its been developed and changed to suit subarus applications

I\'d go with all solid lifters if you have spare heads with them in

Cant say ive ever had to worry about lifters in any of the legacys ive owned but from what i gather there are people who "upgrade" to solid lifters so it seems to be a preferable option

although it wouldnt surprise me at all if both options made little difference

took the motor out today so ill take the other sides camshafts off as well so i will be able to put solid lifters throughout, or just upgrade to a later model heads.
