About 3 weeks ago my 1993 Jeep Cherokee Country over heated to the point that it shut off at a stop sign and I couldn't get it started again. I had it towed to a shop and they found that it was the radiater that was broke. They replaced it and a few hoses and said it was ok. Yesterday when I checked the oil it looked really brown and dirty. My dad said that oil like that is a sign of a cracked block. I talked to the guy that fixed my car before and he said the best way to tell if it has a cracked block is to pour engine coolant directly into the car (not through the resivior), leave the cap off, and start the car. When the cooling system kicks on he said the coolant should rush by if the engine was ok. He said if it was a cracked block it would shot the coolant out line instead of sucking it in. I tried this and it slowly rose up to the top (when the cooling system kicked in) and leaked over a little. It then lowered back down in and looked ok. About 30 seconds later it.....

...rose back up and overflowed a little again. It repeated this 2-3 times but never 'shot out.' Does this mean I have a cracked block? If so, can it be fixed without rebuilding the engine? Any suggestions???

Well, brownish oil may be an indicator of a coolant to oil leak. Let the engine set for awhile and check the dip stick, bubbles of clear mixed with the oil on the dipstick are an indicator of water. Since the coolant was recently replaced, is there an oily film or bubbles in the coolant with the engine running? Oily film in the coolant or air bubbles that don't stop are also indications of an oil to coolant leak or a compression to coolant leak. Another test is a compression test, all the cylinders should be within 10% of each other.
A coolant to oil leak will slowly add to the oil level indicated on the dipstick with a resulting lose of coolant. Another way is to drain the oil into a pan and then pour the oil into a clear container. Water/coolant in the bottom of the clear container is definite indication of a coolant to oil leak. Good luck.

Tapiocia looking oil (green/whiteish sludge) is a sign of coolant getting mixed in. Almost allways by means of a blown head gasket. Repair immedately. Coolant repells oil and will dry your crankshaft bearing resutling in a junk engine. If your block was cracked you would have extreme power loss ie: slow acceleration, doggy sounding idle. Best way to tell is to do a compression check.

Water in the oil makes the dipstick look different. Any change here is notable and consequential. To ignore this difference will invite heartache of the worst kind. Do not procede an any case. This kind of failure will leave you stranded without hope in the most "kind" of situations.Report the breakdown as if your life depended on it. Again' thick brown oil is death for an engine. Do'nt push it!

I would desire to trust Howey. I even have heard to many horror memories approximately those elevate blocks. they're much low-cost, i will provide them that, yet to be extremely secure basically replace the leaf springs. If the inventory leaf springs are in sturdy situation you ought to use an upload-a-leaf to enhance the rear or a lifted shackle. Ebay has some sturdy expenses on those products and that they for regarding a similar cost as a results of fact the elevate blocks. remember that in case you bypass any larger than 3", block or not, you will would would desire to substitute shocks, brake lines or stress shaft to maintain each and every thing balanced. desire this permits.

there would be a white sludge build up on your oil dipstick also, and if the block is cracked you would have a thick white smoke coming out of your exhaust with the distinctive smell of antifreeze. The white sludge in the oil would be caused from the antifreeze mixing in with the oil.

You didn't mention which engine we're talking about... if you have a 4.0 six cylinder, then I agree with sbcadillac. Most likely the head gasket is gone. The 4.0 block and head are nearly bomb-proof.

well if you look on the block, there will probably be a crack, which should tell you if you got a cracked block ;-]
