:o first off.. glad you got the cast off. secondly, i would march my pathy right back to where it came from and have them FIX IT RIGHT. no.. the RMS will not stop leaking once it starts. you better check how much oil they put in too.... too much can be just as detrimental as not enuff.

i would take the pathy back and have them fix it right. you paid for a decent, non leaky job... that's what they need to give you.

if it's not the RMS leaking, it may be the oil pan..... take it back ASAP regardless. :aok: :contract: :furious:

thanks guys, they tried feeding me some stuff about how the engine has 200K on it and the bearings or the shaft must be messed up because it's a new seal... but my other engine had 347K on it and diddn't have a leaky rear main.. do you think this is possible having 200K on the engine or should i still get in thier face about it?

 

so the engine wasn't NEW but it runs GREAT.. it sucks cause my dads friend owns the shop and i'm getting fed up witht them.

 

i'm one of those people that is very patient.. and people will push me and push me and push me... but i'll evntually explode..and explode big... i really don't want this to come to that i just want the pathy fixed and fixed right. i'll post pics of it all later... i'm getting pissed

They're making excuses for a shotty job. If the owner of the shop is your dad's friend, have your dad talk to him and get the tech to fix it right. Now that you got your leg back...go kick some arse! :D

Like Slick I oafed mine on my new replacement motor. I wish I could just take it back and have the $3.99 part replaced. Glad you're getting it taken care of though. If you don't mind, what did you pay for the swap?

Ok I am going to say something very unpopular. If I have it correct this engine is new to you SteeevO. No not a new rebuild but just new to you. Do you have any history on the motor? Was there any indication that the RMS was leaking before the shop worked on it?

 

Now if the shop got the motor for you and warrentied it stop reading right now!

 

If you supplied the motor..... then it may nto be their fault. Please not I am not saying it is not their problem, just not their fault. It is the shop fault IF they put in a poor aftermarket RMS, or they did not install it right. However on any high mileage motor the rear crak bearings can take a beating if lube is not good all the time. This can cause the crank not to turn true, if this happens no RMS will hold for more than a few minutes. The RMS will cover up only a small amount of TIR that is why there is a specification on the crank TIR.

 

Did they put in a cheap aftermarket RMS or install it wrong.... well you will never know. From 30 years of rebuilding motors of all types I will say that RMS leaks are a crap shoot all the time unless the crank has been checked and put into spec.

 

Sorry for the disenting opinion

yes i know exactly what you are saying. the guy before me that had it SAID he took good care of it and was ontop of oil changes. and so far he had been telling the truth about everything else i tore of the parts pathfinder. i even drove the other pathfinder with this engine before yanking it out. it did not leak at all. not one drop .. yesterdayi was parked for 5 minutes and had a oil spot the size of my hand on the ground. the shop also fessed up to putting 5 Qts of oil in after i repeatedly told them it did not take that much. so i am going to supply a factory RMS and also new thowout bearing because they supposedly chaged that too but my old one was ould as heck and sounded like it was ready to fall appart.. and thier NEW one is no better.
