What head gasket is used. Just any one from say a truck? Like a c30? I can do all the work. Just am being told it is a special gasket? But I can't find and info. My RV runs only has smoke coming out tail pipe. I have to move it every 3 days here in the city I live in.

Just a thought here. Most smoking tail pipes are generally  caused by oil consumption...
 head gasket leaks those are water leaks.

Oil leaks burn bluish grey.

Water leaks burn/steam whitish/grey.


More than probably you have a oil leak, valve stem seals. Actually after 20 minutes of running the engine getting it hot the oil burning/smoke  should subside. Does your engine continue to burn oil once it been running for say 15 minutes? If so Valve seals are highly suspected.

Below is a video of this type of fix.

Working on a motorhome engine is not easy no matter how you approach it. That little extra lets him know that you feel his pain.

It also lets them know that should I need to come back to them over the repair issue that I am not there to get something for nothing. My philosophy......Never spend money needlessly..........Save where you can........but never save by squeezing another.

The Payment for the service is one thing...........Then comes the appreciation. Or the other way around.

I generally try to grease the machinery before the work begins.

That's cool dropping some cash on mechanic working on your rig....People should do that more often.

A "pat on the back" goes a loooonnng way, regardless of how it is done.
Slipping him the 50 is a great move - even more so if you are very happy with him.

Quoteany poo that might have gotten loose.

:)ThmbUp.............Good thought and quite accurate ............Especially due to the fact the intake was leaking as well.

I slipped the mechanic working on it a $50 today and told him to enjoy his weekend. I pay the company whatever the agreement + unforeseen without argument but a little cash directly into the pocket of the brains behind the repair without any publicity does wonders. It felt good to see the smile on his face.

 2 or 3 step torque sequence when tightening them they are good.

About the only thing you'll want to do is change the oil quicker. About 500 miles you think Rick? Gives the oil and filter time to flush out any poo that might have gotten loose.

I like what I am hearing because the minute its fixed Im headed south and am not enthused at the prospect of taking off Valve Covers at the second rest area I hit and get out the torque wrench.

I take it that 1985 454  is considered modern.   :)ThmbUp

Rickf1985

No retorqueing needed on modern engines.

stopngo

Do the Head bolts require Re Torqueing after x miles?

They have the VIN #......is that not good enough?   ...............?....sorry
They can tell by the steam holes in the block as long as they know what they are looking for. Yours is in the middle of the generation so there should be no mistakes.

Do you know the part No?? I see yours is an 88.........mine is 85. I checked RockAuto but am a little uncertain.

The Cloyes double roller that Rick mentioned is the one I used.  Nice part.  All '80s 454s should use the same part AFAIK.

     Sorry, for adding to your list of things to think about, but I didnt see that you already done radiator work or what other to do lists that you have already done.
     I have 113k on one unit and i rebuilt the motor for about 1100. but i did most of the work myself.  My other unit has just 33k on it and still runs strong, but if i were doing the heads i would still do the front of the motor.  I have also got 2 setup of 454 vortec and 4l80e trans that I am going to transplant into them.  Just depends on money and what your end goal is. 


     When doing your heads, make sure that they use the correct head gaskets for your engine block. series vs parallel flow. can make for overheating issues.

Mailbox cleaned.
I used 86 as the year since I did not remember what year you had but you got the idea. The super expensive ones you are looking at are for aftermarket roller cams and have a Torrington bearing behind the adjustable cam gear, they also have three or nine position keyways to advance or retard the cam timing. NOT something you need nor would it fit without some work. I like the roller chain since it has a more positive engagement between the sprocket and the chain than does the stock setup, uses just a hair less energy to turn and does not stretch.

Hey! You could go for the gear drive and get that whiny supercharger sound. :D :)rotflmao :)rotflmao

Yeah Rick. Clean out your freakin mailbox.  LOL

Thank you

The
CLOYES C3024K is listed but the only compatible Sealed Power I can find under my 1985 application is KT3171S  and alternatively KT3501SA

One more question.......What is the reasoning behind the huge price variation from 15 bucks to over 300?? Surely the 300 one doesn't do the job 20 times as good..........or???

Just another note.......Your Message box is full.

Rickf1985

I just answered your PM and ironically I gave you the part numbers from Rock Auto. D:oH!
SEALED POWER KT3507S -  Stock replacement set                     $18.93

CLOYES C3024K - Double roller set, My preference.                     $23.79

I did mine, it had about 65K.  While it did have a little slop in it, It would've went on for quite a while longer I believe.

QuoteWater pump and harmonic balancer and boom.

Water pump is actually being replaced (leaking) which I did not mention and is on top of the 900 price I mentioned earlier. Ironically age wise the pump was installed by yours truly in 2004 but mileage wise has only 7 k on it.

Ohhh the dilemma of not using an RV on a daily basis. :'(
