Head Gasket Leak

[Hershey]

well the coolant is remaining the same for both cars . None from tailpipe . No coolant / water ( dipstick or when oil changed twice for dino for both ) in oil pan or oil in the coolant of either YARIS . So , we must have the one you mention . The 2010 was driven for 3 days equaling 260 miles and no oil leak with temps above 80 , as the 2008 leaked for one trip of 179 miles on one 80+ degree day . I'm almost convinced that starting both cars with synthetic at the 1,200 miles is the cause . The 2008 has had synthetic up 21,000 miles while the 2010 for little over 5,000 miles . Hopefully the lesser use of the syn will help the leak stop for the 2010 . Hate to get both engines torn down . An acquaintance had to get a head gasket replaced at 5,000 or so miles on a FORD Focus under warranty and never ran that good after the fix . We'll keep our fingers crossed to have the leaks stop .
