ok doke . one of the myriad of things i'm looking to fix and /or play with whilst bessie is sitting on her throne in the garage is a somewhat scary issue . here as of late she's been { the 53 } getting a little pressure in the cooling system . got to put about a gallon every 3 days in her cause it will force it out the over flow . i dont know what is causing this just kinda geussing , but i have run a compression test to see if i had a leaky head gasket and nothing showed . she does not have thermostats in her so i dont know if maybe it's due to that . everything seems to be fine she doesnot run hot . while we had it apart i seen no visible problems . i am gonna take the heads back off and was wondering if you guys got any suggestions as to a test to check the valve seats for cracks in case they are not visible short of magna fluxing it and or possible probs i may not be seeing . .i'm also gonna replace the da-- head bolts like i should've already in case they were stretched .now if everything checks out i was entertaining the idea of milling the heads to gain some on the c.r. how far is adviseable on her . stock 8ba. last question i swear !! one of the bonusses i got with the 49 was a set of truck water pumps , extra laying in the back . good place to send 'em and get 'em rebuilt or just go with the new , improved products from the aftermarket ?????? oh yeah shims on the bolts i'm assuming if i mill ? sources or just plain ol washers ?

 

HEY KEVIN, ONE PROBLEM I HAD WITH THE MUSTANG 351 CLEVELAND WAS THAT THE RADIATOR CAP APPEARED TO BE GOOD BUT WASN'T STAYING PUT UNDER PRESSURE, IT POP UP JUST AS SOON AS IT WARMED UP AND STARTED FLOWING OUT TO THE OVERFLOW TANK ALSO. PUT ON NEW RADIATOR CAP AND "PRESTO" OR DID I MEAN TO SAY
"PRESTONE" THE NEW CAP FIXED IT. MIGHT TRY THAT, MAY SAVE YOU SOME TIME AND MONEY. SEE YA TIM

 

never even thought of that as i was bracing myself for the worst . think i'll go around the corner tommorrow to the boy's in green .
