Hey guys, 96 outback 2.5 dohc, just had heads machined, valve job, new subaru mls gaskets, new t belt, all gaskets, seals etc. passenger side head is got a loud valve tick. Not normal sound. Not bottom end, light and tinny sounding. Sounds like back passenger cylinder. Stuck lifter? Car runs decent, no leaks besides water pump(going to fix) jus afraid of running it too much with this noise. Running Dino 10-40 oil. No leaks, just resealed everything. 4 1/2 quarts of oil. I triple checked the timing belt marks, and everything is dead on. Some friend of mine told me I have hydraulic lifters in 1996 model, and that one could be stuck? Should I pour seafoam in the oil? Marvel oil? Pull the camshafts out and free the lifter? Please someone help... I have been fixing this car for months(due to funds) any ideas which is the best approach?
