Hi, I have read the "Known faults of 1MZFE engine" and "diagnose the oil leak". I found engine oil leak on my garage floor so I went for a car check and the mech (not my usual workshop but is near my home) told me a faulty head gasket causing a massive oil leak. I told him only 1-2 drops every few days and he said that is considered bad enough. If you read my previous post, I drove a 98 V6 Conquest (just bought). Timing belt changed by previous owner at 110,000kms. Currently at 185,000kms. Because of the oil leaks, mech said the oil should have already gone through into the timing belt and it needs to be replaced. He ask if I want to get it repair for around $800-900. My eyes popped wide and jaw dropped!! :( I told him I will think about it. He said the belt might seize anytime. Anyway, as I am going to have a road trip maybe close to 10,000kms in 2 months time, I will go and get this sorted out at my usual mech (quite far from home) soon. Will ask him if it affected the timing belt. Ok, lets say it is only just to replace the faulty gasket which causes the leak, how much roughly would I be looking at? I am asking because I dont know what is the market rate. Also, how long will this replacement take? Thanks
