1570 blowen head gasket part 2

well guys i think i found the problem, it was what THAD said about rain water got in from the air cleaner. i started taking it back apart tonight and when i pulled the air cleaner off my leg got wet, when i got the air intake tube off the side and i looked into the middle head it was full of water. so when i tryed to start it yesterday it just sucked all the water in and blew the new gasket out the side of the block. i am going to take the head up and have it checked to make sure it is all right. i also checked from the top edge of the sleeve to the top of the piston and i have a .005 diffrence between pistons 3 and 4, i was checking to see if i bent a conneting rod. i think that is ok but you guys tell me what you think as i am not 100% positive. i did not have the metal cover over the air cleaner on mine tractor yet and all 3 tabs are broke and i was looking for a way to fix it, i guess i should have layed it on there when it was parked. does anyone know why case made the 1570 with the top of the air cleaner with out a real cover, i have a 2470 and the air cleaner on that one has a top that seals like most air cleaners do. i want to thank all you guys for the help.

You always feel better when a cause of the problem can be found, a good call by Thad because far to often we over look the simple obvious things. I don't know if that .005 is reason for concern, I'm willing to bet if you checked that measurement on a know good set of rods in a engine you will find a difference also. The 12, 13 and 1570 do not use a direct cover over the air filters and rely on the air filter its self with that depression to hold water and dirt. Had they made the center higher the problem would not occur as often. I would get a piece of light tin or flashing and make a cover that could be slid into the opening and down on the filter acting as a roof for it. Rod.

Im glad you at least found the problem. Im with Rod i dont think the .005 would concern me. I have seen this happen to many times to count and dont know of one that had a bent rod. Now the 451s have alot lighter rod and they will bend everytime. You will just notice a miss in them and it usually chips the bottom of the sleeve also. Thad

Does this or can this happen to a 1370?

I dont own a 1570 but I would like to see a picture of what you guys are discussing as far as the breather letting water into the head.
