The silver gasket is a crutch for slightly warped manifolds (take that to mean the faces of the manifolds need to be checked to make sure they are not warped). All you should need is the blue one which is intake only (factory did not use an exhaust manifold gasket). To install it properly, the manifolds need to be loose to each other before you put them back in. You can read about the procedure at http://www.mattsoldcars.com/RestoreAmerican/loose_intake.shtml.

 I made  tapered aluminum pin and pressed it in. For the intake and exhaust gaskets. The Felpro 1981 gasket kit came with 2 intake gaskets? Do you install the exhaust/intake intake and the intake intake over it? I think that how it was originally.]]> Wed, 03 Feb 2010 20:02:48 +0000 http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post146156.html#146156 Oiling Issue Resolved, but the damage is done : farna wrote:I wasn't... http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post145441.html#145441 Author: poormansMACHINE

No prob.
My fault for not having my Little Orphan Annie decoder pin set to the correct position to decode the year.LOL

Hmmm.... I'm going from all the AMC car documentation for the year on the engine code. There's no reason AMC should have used a different coding system for Jeep, but I don't have any Jeep TSMs.  Still, I'm confident that Jeep used the same engine codes.  I double checked my 75 TSM, and it does have 7 for 1974, 8 for 1975, just to make sure.  

I wasn't trying to embarrass you or anything, just pointing out the error. At least the last number of the year would be the natural assumption, not like some of the errors I've made here in the past! We all make them on occasion.

Nice to know on the oil filter adapters! So any filter that AMC used on the sixes and V-8s with oil pump mounted filter (at least the 64+ 232 family) can be used with the right adapter. For those who don't know, the adapter is just a double sided bushing that threads into the block with a hex "head" in the center. One side in block, the filter screws on the other side.

The 1988 4.0L block I used to build my stroker with used a metric filter. I noticed that the filter adapter unscrewed from the block on the 72 donor 258 and the 88 4.0L. On a whim I unscrewed both and low and behold, the 72 adapter screwed right into the 88 block! Not 100% sure if later model 4.0s would do the same, but I suspect they will -- at least all that use the metric filter.


I went off the 74 Jeep TSM for the code but didn't look closely at the year..
First character year, second and third character month, fourth engine type, fifth character day.

The 6 ans 8 share the same thread on the "engine side" (block on the 6 and filter adapter on the 8).
Engines be it 6 or 8 used metric filters through the Renault period and had a sticker on the firewall noting this. 91 and newer use the Ford/Mopar 3/4 thread.

As long as the lifters have that oil hole in the center where the pushrods sit sounds like you're all set!

I was thinking some RTV on the block in the head gasket slot, not directly in the oil hole. Of course it would need to set up before running too. I don't think that would be a problem at all. But it shouldn't be necessary at all. ]]> Sun, 31 Jan 2010 19:13:16 +0000 http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post145191.html#145191 Oiling Issue Resolved, but the damage is done : Thanks again for the input.

Thanks again for the input. Having the newer filter and the 2V carb w/ newer intake created the confusion. This now being a 232 should not create any other issues installing a 81 258 head. The pushrods were the same length and the purchased lifters for the 81 258 looked to be dimesinally identical.]]> Sun, 31 Jan 2010 18:59:39 +0000 http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post145187.html#145187 Oiling Issue Resolved, but the damage is done : PMM is incorrect on the... http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post145178.html#145178 Author: farna

PMM is incorrect on the year for your engine. Everything else is spot on (the "E" is 232/1V to be more exact -- factory 232/2V would be "G"), he just forgot about one little thing...

AMC didn't start using the last number of the year for the year code until 1980, also the first year they used a zero. Before that year code started with the number 1 for 1959 and was consecutive from then on. 1960 was "2" because zeroes weren't used (to prevent confusion with the letter "O").

When it got back around to 1968 numbering started over with 1 (67 was 9, started over with 1 for 77 too). You have to know about when an engine size/type was produced for the code to be much good, but the letter code mostly takes care of that. There are a few letter codes that repeat, but they are usually noticeable ("A" could be a 60-65 196 L-head, 1970 199, or 71-79 258/1V... could be some confusion between the 199 and 258, but they have different block heights and strokes). 

A "5" year code would be 1963, 1972, or 1985. There were no 232s or 258s in 63, and it has the oil passage for shaft rockers, so it has to be a 1972 block. Takes a little homework to decipher the exact year in some cases!

The 1988 4.0L block I used to build my stroker with used a metric filter. I noticed that the filter adapter unscrewed from the block on the 72 donor 258 and the 88 4.0L. On a whim I unscrewed both and low and behold, the 72 adapter screwed right into the 88 block! Not 100% sure if later model 4.0s would do the same, but I suspect they will -- at least all that use the metric filter.

There are 3, small housing filters.
Early (up to 86) with 13/16-16 thread
  late 87/90 with a 20mmX1.5mm thread
91 and newer with a 3/4-16 thread

 Thanks, I guess that makes sense the 87/90 oil filter is a small housing but shares the same threads as the older ones. This motor has a newer intake and exhaust manifold. I guess that threw me off as well. So a 75 motor has the shaft style rockers? I found a piece of delrin which will make a good tapered pin to seal the hole. Thank you all for you'r input.  ]]> Sun, 31 Jan 2010 17:47:37 +0000 http://theamcforum.com/forum/oiling-issue-resolved-but-the-damage-is-done_topic12597_post145165.html#145165
