i have 122k on my 99. i noticed the HGs leaking about 30k miles or so ago
but i plan to pull the engine and do the HG, valve covers, plug seals, cam seals, front crank seal, oil pump seal, timing belt, tensioners, water pump, oil pan and anything else i can find! is Subaru the only place i should get the HGs from since they are MLS? you does Felpro have them now? Ive heard Felpro is the best aftermarket gasket company. i used that conditioner and it stopped the leak for a couple months but it comes right back. its a good thing its only $1.50!
