what is the best way to clean the engine block before i put new gasket and install the heads?
thnk you

 

I typically use a razor blade to get rid of any residual gasket/sealer, then I clean the surface with paint thinner and let air dry. Never had a problem with leaks due to a poor seal using this method.

 

my mpv uses 4 layer metal gasket

 

So long as both surfaces (head & block) are clean, you should be fine. Not sure if you've got a service manual or not, but the sequence of torqueing the head bolts down is critical to getting/maintaining a proper seal. I'd recommend either a Haynes or Chilton's manual, but be sure to look inside to see if it has the information you are looking for. I've seen some manuals be very detailed while others had less information than the owners manual.

 

that is one of my problems my local auto parts don't have a manual for my mpv only 89 to 1995 and 1999to 2004 or 05

 

What year is your MPV?

the books on ebay will take a week to get they don't want to send express mail or any faster i need to put this engine together this weekend
and that is all i need to know,what is the sequence of torquing the head screws and how many pounds
I believe to start in the midle and then front and back untill they are all even i can believe there i sno much information
there is a site that charges 20 for online manual but i didn't find it or they don't have MPV instructions

 

Try going to your local dealer and ask them if you can see this part of their manual. I've had some let me take a photocopy of the pages I needed.

 

I got it last night, i pay for 1 year of ALLDATA last night so i am going to work on the engine now
thank you
