loud clicking at startup equals rpm, then goes away
loud clicking at startup related to rpm. Sound goes away after several minutes. Repeats
with less noise after second start after 10 minute trip. Could it be a leaky check valve in
oil pump? It is not exhaust related. Continous belt is not dried, cracked or checked.
Ambient temp is in 50's.
Sound,s like you may have a weak lifter.
Could be either a tight ristpin or a rocker if it's a 4.0 most likely it's a rocker they are known for take changer ur oil get thicker oil and use some oil treatment in it
