240playtoy Posted May 16, 2005 Share Posted May 16, 2005 I recently started up on my hybridization of my '71 240. A lot is planned for it but the heart will be a '93 LT1 ripped from the chest of a Firebird with a 6-speed strapped on. Yes, I get to learn to program chips because of my '93. Anyway, my poor engine, not having been cleaned prior to removal, had its intake taken off for removal prior to shipping to me. Well, evidently there was sand on the engine, because I found some in my engine. Any good ideas for getting it out w/o having to take the whole thing apart? I also attached images for my engine, it'll be sitting in a black engine bay and the car will eventually be dark green (of some sort) with white stripes, possibly reminiscent of 70's mopars.

Bartman Posted May 17, 2005 Share Posted May 17, 2005 Welcome to HybridZ, and good luck with your Hybridization! Where did you find the sand in your engine? I would think that you have a possibility of sand getting into the combustion chamber of any cylinder that had the intake valve completely or partially open. If this is possible I don't know how you could get around having to remove your heads:icon56: . Is there sand in the crankcase? Quote Link to comment Share on other sites More sharing options...
240playtoy Posted May 17, 2005 Author Share Posted May 17, 2005 Found the sand in the lifter area, I figured the sand was between/on the heads and intake when the intake was removed. So it possibly could have fallen into intake and exhaust ports, yes, but I found most of it by the lifters. There are oil drain holes in that area that drop to the cam. The pan has yet to come off as I just recently got it on a stand. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted May 17, 2005 Share Posted May 17, 2005 The sand was very likely from the intake. The factory tends to leave a bunch of sand from the mold in the intake. If you pull the intake, remove the splash pan from the underside, you will likely find sand in the bolt holes, or in the threaded plug holes under there...... As for getting the sand out.....have you run the engine already....if not, you might be able to just carefully mop it out, or vacuum it with a shop vac.....

Here comes trouble Posted May 17, 2005 Share Posted May 17, 2005 For the money you have in that set-up..... remove the heads and intake and clean using vaccum and air pressure... wipe with an oily rag (Lubriplate works good and tends to make crap easily observable) Drain the oil and fill crankcase with diesel fuel (very inexpensive cleaner for engine insides)..replace oil filter. then carefully with frequent inspections and cleaning by all methods at your disposal turn the crank with socket and ratchet. While I was away someone borrowed my Datsun pick-up and blew a head gasket with oil getting into the water system and water into the lubrication system. Number 3 cylinder set for over two years with water in it and on the full down stroke! Water was still present when I took off the head.... (so I still got good rings ? I hope)... Basically what I describe above is what I am doing to the L20 B engine.. I got the pistons free without breaking the piston rings by soaking the tops with a WD 40 and Lubriplate cocktail. If you spend some time and be careful you will get the sand out even if it has traveled all the way to the oil pan. Some may question this method but it will work but will take time... I would actually remove the oil pan and clean it before flushing with diesel if the sand is present in the oil pan.. Quote Link to comment Share on other sites More sharing options...
jbk240z Posted May 17, 2005 Share Posted May 17, 2005 If I were in ur shoes, I would pull the heads, oil pan, camshaft. Use one of those little inspection mirrors, and inspect VERY carefully. If any sand is in the cam bore or oil galleries, take down the whole motor and clean accordingly. In my book, the price of a gasket set, and a weekend, is alot better than rebuild/rebore, new cam, bearings, etc. Anyway, good luck!! Don't take a chance, it's not worth it.

Guest 305240 Posted May 17, 2005 Share Posted May 17, 2005 I have to agree with jbk on this. It's already on the stand, pay a little now, or you may have to pay a whole lot later. Cheap insurance if you ask me. Quote Link to comment Share on other sites More sharing options...
240playtoy Posted May 17, 2005 Author Share Posted May 17, 2005 As per tim's question, the engine hasn't been run since it was shipped. I am pretty sure the sand wasn't from the original casting of the intake because: 1) the engine was from Los Angeles and the surrounding bay area, and 2) there was sand in the lip of the valve covers. Sand under the intake was taken out with my finger and a paper towel to wipe it on. Here comes trouble, I had gotten some advice from others around here similar to the filling with diesel, using kerosene and a bug sprayer... that's if the kerosene is nice to the plastic. But, it seems it may be total teardown time. Thanks for all the advice guys. Quote Link to comment Share on other sites More sharing options...
