junkyard teardown of diamite

[paduster]

thinking of getting the 10:1 pistions out of it and plan on getting the cams too but how hard is it to pull the pistions without pulling the motor and easiest way since i will be in the dirt doing the work. dont want the whole motor as this place is $$$$$ and might even just toss the pistions over the fence. and get them after i leave. and another question on these pistions what rings do i buy for them???

[Sundance 6g72]

Ed got a set of 91.1mm chrome rings from Summit Racing and I did the same. I just got the 1.2 1.5 3.0 ringset that matches up with 1992+ motors that are oem 8.9:1. 8.85:1 motors in early years are 1.5 1.5 and 3.0 and are beefier if you want oem pistons because the top ring is located much farther down.

talking about the stock pistons. that should be a good starting point.. cant see why the rings would be different.


you could pull the oil pan, pull the crank and then pull the rods and pistons out but iirc new set of 10:1 cast pistons is like $150. thats so worth it.

[shayne]

pistons wont come out the bottom as far as i could tell on my block, the main bearing webs look like they get in the way of the piston skirts trying to come out the bottom. p.s. dont throw pistons over a fence unless you want to chance ruining them by bending a skirt or chipping them.

[paduster]

If anythingi knew I would have to tear the oil pan off and heads to get them out but my qtuestion was anyone got any quick tips minus the ones like cut timing belt and hoses just to get them out the way quicker. And i wasn't going to toss them over really more like pull the fence up and slide them underneath it I know the crank won't come out all the way without removing the trans and oil pump. I should be able to get heads off then oil pan then rod bolts then all out the top.

Main question is are the rings differnt

[shayne]

the rings should be whatever came stock, like npr moly rings or? and the bore should be 91.1mm unless somebody already has dug into it to bore it out. look closely at the piston crowns though, as some diamante's didnt come with 10:1 motors( ive read about this). if you want them, yank em, clean them and use them if the skirts are not scuffed up or scarred.

Or maybe, don't throw the pistons over the fence because that's stealing :). Perhaps the prices would be better if everyone paid for their parts?

[Sundance 6g72]

if its a car i dont care about, ill cut everything apart but i like to take care when its a 3.0. someone might want that timing belt, or hose. i dont know how id be able to tell a fellow 3.0 guy, "o yeah im the one who cut the harness in a million peaces and trashed the engine bay just to get some injectors, or in your case, pistons"

id just buy a set off rock auto.. $150 and they are brand new (IIRC) What would you do with that perfectly fine set of heads? re install them? lol

Or maybe, don't throw the pistons over the fence because that's stealing :). Perhaps the prices would be better if everyone paid for their parts?

:amen:


But anyhow, yeah, not much you can do to lessen the work, oil pan, rod bolts, intake, valve covers, heads.

[Sundance 6g72]

oil pan requires removal of front motor mount too.

seems like to much of a hasle to teat into the motor and find a couple of the pistons shot or something.

cams on the other hand are easy to pull :)

[paduster]

Then how about a link to where I can buy them that cheap cause i would rather pay for them bit at resonable prices they are no where close and are just that ignorant so that's y I do it there and really only there. Now if I can buy them for a decent price I will. Plz send me a link

And i ain't to worried about the cams i am in contact with turbovanman and looking to get cams to match the limits of the head in stock from - the rockers I am trying to make and test I want a cam worth testing and this should be fun

[Sundance 6g72]

id look them up for you but im super busy

just go to rock auto and search for the correct year car and post the link and others will comfirm if they are correct.

[paduster]

not sure on the year but guessed 95

and all the way up to 97 when the motor changed to a 3.5 all with the same part number

[Ondonti]

bare shortblock should be cheaper then buying anything separate. Mitsubishi cars tend to be care for much better then Mopars so the motor often looks 100x cleaner inside and will likely have decent ring seal.

[paduster]

Well can ask him much they want for it but it doesn't have a hood and the front valve cover is already off when i found it was going to buy whole motor u thing it is still worth it

[paduster]

well they want 200 dollars for just the short block and 10 dollars to lift the motor out i gotta get it ready so if anyone can tell me for sure which one is the 10:1 pistons i will just buy the short block even though i have bought full motors that are running for that price


i dont think these cars have any better cranks then ours do they

[Sundance 6g72]

crank and rods are the same.

id buy the motor but i cant fonfirm the year.. i just assumed they were all 10:1 :(

[Ondonti]

1992 = 10:1. I have never heard of a non 10:1 diamante though. Listings for replacement parts are often incorrect.

Can you pull the front head and then give up without paying anything?

Turn the crank and make sure it turns freely 360 degrees if the VC is missing. The motor I ran 11.5 with was actually seizing from corrosion due to a missing valve cover until I soaked it down with deep creep. Obviously being free'd up doesn't make it a great cylinder.

[paduster]

yea i was working on that yesterday and ran out of time i will be going back sometime this week to finish getting the heads off and getting the cams and short block ready to pull. are the heads worth grabbing too. they don't get paid till i get the part so i will find out if they are good or not

[Sundance 6g72]

heads are the same as ours though i would not bother grabbing them sense the valve cover has been missing. do your self a favor and get the newest set of heads you can (96 +). chances are they have the good c clip valve guides and had less abuse.

also, dont be like.. remember the rocker assembly for each head is only good for that specific head!

[paduster]

ok well whatever head i get i am doing so experimenting with i am trying to come up with a solid rocker mod using the stock rocker with a insert where the lifter goes. just trying to get all the pieces together to build the motor

[Sundance 6g72]

would be cool if you came up with a solution!

I think 92 was the first year to get c clipped valve guides but i also think that your 92 could have a build date in 91? thats why i say get a late model one if you can.

[paduster]

well i have nothin for this motor yet getting the shortblock hopefully this coming weekend and i have a set of heads but a bolt hole is striped out that holds a czm bearing(and the people i bought it off of swore it was a good motor) to bad that wasnt the worst thing i found either. now since i am using those rockers as the test rockers for the solids. now i was thinking of getting a full motor out of a dodge car so i get all of the mounts and brackets needed since the shell i am looking at doesnt have them. so it might be cheaper to by a good dodge 3.0 as well as the diamante shortblock. now once those are all here i can start putting the rockers togther. i have been in contact with turbovanman and asked for a cam to get done to max the stock lift of the head and to have a useable powerband up to 8000 to fully test my rockers. lets just hope nothin comes up in life so i can accully keep working on this first and not something like billls and life lol.

[Ondonti]

My 92 motor ended up having C clips on the exhaust valves. I had thought that I dropped a guide when I was smoking but it was my big cams/solid rockers that had smashed the seals.
