Hi guys. Sorry for the late reply had issues logging in. Just an update. I had a cylinder leakage test done today and cylinder 4 has water inside. Also spark plugs were wet and need replacing. so therefore it is a blown head gasket. How much should a head gasket replacement cost labour /parts? The garage near me who done the cylinder leakage test first said 700 just labour. Then spoke to his mate who said its a big job and he said roughly may be 1300/1400 but will confirm..so he doubled. Then said 2k with parts included apart from new spark plugs and timing belt (recommend changing and i was thinking to anyway as labour is included) he is over pricing me for sure although hes work is professional. Can any1 tell me what do you think? Also how much i should be looking at?

Thanks for your reply. This is what i have been advised by my local mechanic. I believe water has now got into the oil mixing. I have some pictures.

Hi. I am new to the forum. I have a 93 TT auto Jap import. I will explain in detail as much as i can as to what i have been experiencing. I am a newbie to cars but I have learnt a lot recently and continue to gain knowledge and experience. I really need your help as i am very stressed with my Supra lately. Any help will be appreciated. sorry for the long post i have a few issues but can be all inter related. So everything was fine with my car apart from issues with starting the car up (i would have to jump start it, i tested my battery and alternator with a multimeter and they are fine) I went to fill up and drove the car hard there and back. 5 days later (16th June) i started the car and drove few miles. When i got back in the car to drive back home after starting the car the exhaust sound was deep for around 5 seconds and then went normal like it opened back up. Very strange first time this ever happened. Got home and then i headed back out. This time i reversed out the driveway and car jerked a little. It also did not sound normal almost like its misfiring. I then left from that place to come back home and on starting the car it would shake/vibrate. Then on the 24th June i thought let me take the car for a spin around the block to see how it behaves since my last experience. The car lacked power! acceleration was poor, gear changes were fine and sounded ok but was just was sluggish like its holding back power. Ever since that day (June 24th) i did not drive until the 5th July i decided to take the car to the garage to get it looked at. On the road just before the garage i decided to turn the AC on (it was a hot day!) i noticed my temperature gauge go up to 3 quarters of the way. I pulled in to the garage and turned the car off immediately. Told the mechanic and he said water/coolant must be low which it was. Basically took a whole gallon of water. I noticed the sound of the engine and exhaust went quiet. Almost as it has calmed down and back to how it normally should be sounding. I checked the water level in the radiator a few weeks prior and it was full. So it must have leaked or where else would it have gone? after leaving the garage i stopped at a auto part shop which done the free battery test for me. While doing the battery test even he noticed how hot my engine bay is and confirmed my battery is good, can do with a charge but seems fine. He did not have a alternator tester. Anyway so on my way home the car was pulling good, better acceleration and power. I decided to turn the AC on again and the needle started going up back to 3 quarters high. I quickly turned the AC off and it slowly came back down to the middle. Now the very next day thinking my car wont start as its got a mind of its own (intermittent starting) it started and i went to my friends house who had a multimeter to further test the battery/ alternator which were fine. While my car is idling it is idling rough, like it is misfiring and the exhaust/car in general vibrating. After some driving i noticed the car in traffic was jerking at low speed coming to a stop and the rpm was very low like the car is about to stall. white smoke occasionally would come out but i also have a valve stem problem which needs replacing (well that is what i was told by who i purchased the car off. he gave me brand new stem seals with the car) and i think that is related to that. After reaching home and an hour and a half later i decided to top the radiator with water and it took a few jugs! The engine bay and hose pipes were VERY HOT. Car would not start. Very loud thump sounds trying to start the car. I had to push it to and onto my driveway! 10 days later today without the car being started i decided to check the water level in the radiator. It took a lot of water considering it was sat and not started or driven. Therefore i decided there must be a leak of course. Hoping its just a hose which i can replace and then flush the radiator and have fresh coolant. so i jacked the car up and checked the hoses which all seem fine not cracks or tears apart from the small hose on the bottom end which seems easy to turn but again no leak. Upon starting the car the exhaust shoots out some water and i noticed from the rusty radiator the exhaust had that same rusty water. You can see it in the exhaust. car sounded awful. I had a friend go underneath and he assumed the water is leaking from the top somewhere as he said a lot of water dripped down. So we undone the radiator bolts and the fan shroud to pull the radiator up thinking there is a leak in the radiator. We started the car and there was no leak anywhere. i was expecting water to pour out of a hole in the radiator but nothing! then i said lets check the engine oil. we opened the cap and can see a little water in there. its also is on the dipstick started to get milky. i only started the car and moved it to another spot on my drive way. checked water and had to top it up again. after starting engine topped it up again. so where is the water going! no way i can drive the car even to the garage. needs to be towed. Me and my friend have come to a conclusion that it can be a blown cylinder head gasket. What does not make sense is it over heated approx 3 times going 3 quarters not in the red or near so why would it blow the head gasket. Also if there was a leak where was it leaking or was it going in the engine? as some water is coming out the exhaust also. I do think the coolant was low or none in there just water and due to the hot weather it took a toll and i left the radiator flush late to where it has now starting mixing with the engine oil...passing the head gasket and going in the engine? if i done the radiator flush earlier if i knew and put toyota red in it would of been fine that is if it never leaked. If its head gasket it will just need to get replaced with radiator and engine oil flush right? If its not got to that stage what would you advise? i was thinking to do a radiator flush today but it may be a waste of time as water is dissappreaing and i do not want to start the engine any more to cause more damage. what do i do?!! please someone help! To summarise and Conclude: starting issues - not the battery or alternator Can not be the starter as it starts with jump leads or starts randomly when it wants. Can be coil packs as car struggles to start but also is running rich and felt like its going to stall (low rpm) Or is it radiator/head gasket related? radiator/coolant/head gasket related: with AC on car temp spikes Car in general gets hot and temp is going up now regardless water is dissapearing from radiator maybe going into engine oil and not a leak?
