Whats more expensive, set of lifters and pushrods or an engine rebuild?

That being said he has no idea what`s wrong so who knows what it is.. just a guessing game at this point

Heres my experience/opinion on it: I used Morel lifters (hyd rollers) when they became a "thing" back in 05/06, running 180/195 seat and close to 500 lbs open up to 6300 in my own blower engine WITH 20/W 50 oil. Never had a tick or issue. Retired them at every refresh interval at about 100 hours. Also used them in quite a few customers builds with no issues regardless of oil weight. Fast forward, no matter what lies CHRIS S####B, JOHN C#####S perpetuate, around 2014 they changed something. They sped up production, sent lifter bodies to Mexico or China, IDK BUT they started having failures , plungers failing/sticking. tie bars breaking, roller wheels disintegrating. CHRIS SXXXXB in conversation on FB made THIS statement: They ONLY have 1 pair of lifters out of a 1000 sets that fail, thats funny because I flow/clean injectors for several other engine builder/dyno guys in this business and EVERY SINGLE ONE OF THEM HAS HAD FAILURES and will never buy Morels again. The comps are a step below, seen guys have failures on street engines before 5000 miles with them.
As far as hyd flat tappets, the ONLY engines I build with them anymore are class rule engines that dictate you run them (which is rare for me), and I wont warranty them in any way, shape or form. I put it in writing that any failure is customers problem and make them sign it as cam core/lifter construction has went right in the trash..Ive used johnson lifters successfully in last 40 or 50 mild bbcs ive built with no isuues.
I had one customer who i used the Morels with from that 2014/2015 era, in 2019/2020 Bob M who had sold them to me asked if customer had any issues with them. I said NO except they were noisy cold. He highly recommended changing them before they failed. I mentioned this to the customer who said nah, Im selling boat soon anyways, not worried about it. a couple rides later one failed and destroyed his cam, lifter bore etc and trashed his whole engine. Was around 150 hours IF I remember correctly

Anyone know who makes them for comp this day and age?

When my builds were in the dream stage the lifter subject was on roids so I went solid and never looked back. Really glad I did and just ck lash once a season! The solids in a couple of my muscle cars rarely need an adjustment when I ck those about every other year now.
